fix(deps): update rust crate clap to 3.2.25 - autoclosed #1094

Moved deprecations to be behind the deprecated Cargo.toml feature (#3830)
- For now, it is disabled by default though we are considering enabling it by
  default as we release the next major version to help draw attention to the
  deprecation migration path

Compatibility

MSRV is now 1.56.0 (#3732)

Behavior

Defaults no longer satisfy required and its variants (#3793)
When misusing ArgMatches::value_of and friends, debug asserts were turned into panics

Moving (old location deprecated)

clap::{PossibleValue, ValueHint} to clap::builder::{PossibleValue, ValueHint}
clap::{Indices, OsValues, ValueSource, Values} to clap::parser::{Indices, OsValues, ValueSource, Values}
clap::ArgEnum to clap::ValueEnum (#3799)

Replaced

Arg::allow_invalid_utf8 with Arg::value_parser(value_parser!(PathBuf)) (#3753)
Arg::validator / Arg::validator_os with Arg::value_parser (#3753)
Arg::validator_regex with users providing their own builder::TypedValueParser (#3756)
Arg::forbid_empty_values with builder::NonEmptyStringValueParser / builder::PathBufValueParser (#3753)
Arg::possible_values with Arg::value_parser([...]), builder::PossibleValuesParser, or builder::EnumValueParser (#3753)
Arg::max_occurrences with arg.action(ArgAction::Count).value_parser(value_parser!(u8).range(..N)) for flags (#3797)
Arg::multiple_occurrences with ArgAction::Append or ArgAction::Count though positionals will need Arg::multiple_values (#3772, #3797)
Command::args_override_self with ArgAction::Set (#2627, #3797)
AppSettings::NoAutoVersion with ArgAction or Command::disable_version_flag (#3800)
AppSettings::NoHelpVersion with ArgAction or Command::disable_help_flag / Command::disable_help_subcommand (#3800)
ArgMatches::{value_of, value_of_os, value_of_os_lossy, value_of_t} with ArgMatches::{get_one,remove_one} (#3753)
ArgMatches::{values_of, values_of_os, values_of_os_lossy, values_of_t} with ArgMatches::{get_many,remove_many} (#3753)
ArgMatches::is_valid_arg with ArgMatches::{try_get_one,try_get_many} (#3753)
ArgMatches::occurrences_of with ArgMatches::value_source or ArgAction::Count (#3797)
ArgMatches::is_present with ArgMatches::contains_id or ArgAction::SetTrue (#3797)
ArgAction::StoreValue with ArgAction::Set or ArgAction::Append (#3797)
ArgAction::IncOccurrences with ArgAction::SetTrue or ArgAction::Count (#3797)
(derive) #[clap(parse(...))] replaced with: (#3589, #3794)
- For default parsers (no parse attribute), deprecation warnings can be
  silenced by opting into the new behavior by adding either #[clap(action)]
  or #[clap(value_parser)] (ie requesting the default behavior for these
  attributes). Alternatively, the unstable-v4 feature changes the default
  away from parse to action/value_parser.
- For #[clap(parse(from_flag))] replaced with #[clap(action = ArgAction::SetTrue)] (#3794)
- For #[clap(parse(from_occurrences))] replaced with #[clap(action = ArgAction::Count)] though the field's type must be u8 (#3794)
- For #[clap(parse(from_os_str)] for PathBuf, replace it with
  #[clap(value_parser)] (as mentioned earlier this will call
  value_parser!(PathBuf) which will auto-select the right ValueParser
  automatically).
- For #[clap(parse(try_from_str = ...)], replace it with #[clap(value_parser = ...)]
- For most other cases, a type implementing TypedValueParser will be needed and specify it with #[clap(value_parser = ...)]

Note: clap v3 has been in development for several years and has changed
hands multiple times. Unfortunately, our changelog might be incomplete,
whether in changes or their motivation.

Highlights

A special thanks to the maintainers, contributors, beta users, and sponsors who
have helped along this journey, especially kbknapp.

StructOpt Integration

StructOpt provides a serde-like declarative
approach to defining your parser. The main benefits we've seen so far from integrating are:

Tighter feedback between the design of clap and the derives
More universal traits. Crates exist for common CLI patterns
(example)
and we've re-designed the StructOpt traits so crates built on clap3 can be
reused not just with other derives but also people using the builder API.
People can even hand implement these so people using the builder API won't
have the pay the cost for derives.

Custom Help Headings

Previously, clap automatically grouped arguments in the help as either
ARGS, FLAGS, OPTIONS, and SUBCOMMANDS.

You can now override the default group with Arg::help_heading and
App::subcommand_help_heading. To apply a heading to a series of arguments,
you can set App::help_heading.

Deprecations

While a lot of deprecations have been added to clean up the API (overloaded
meaning of Arg::multiple) or make things more consistent, some particular
highlights are:

clap_app! has been deprecated in favor of the builder API with arg! (clap-rs/clap#2835)
Arg::from_usage has been deprecated in favor of arg! (clap-rs/clap#3087)
- Porting example
The YAML API has been deprecated in favor the builder or derive APIs (clap-rs/clap#3087)

BREAKING CHANGES

From clap 2

Subtle changes (i.e. compiler won't catch):

AppSettings::UnifiedHelpMessage is now default behaviour
- {flags} and {unified} will assert if present in App::help_template
- See clap-rs/clap#2807
AppSettings::EnableColoredHelp is now the default behavior but can be
opted-out with AppSettings::DisableColoredHelp
(clap-rs/clap#2806)
App::override_usage no longer implies a leading \t, allowing multi lined usages
Arg::require_equals no longer implies ArgSettings::ForbidEmptyValues (#2233)
Arg::require_delimiter no longer implies ArgSettings::TakesValue and ArgSettings::UseValueDelimiter (#2233)
Arg::env, Arg::env_os, Arg::last, Arg::require_equals, Arg::allow_hyphen_values,
Arg::hide_possible_values, Arg::hide_default_value, Arg::hide_env_values,
Arg::case_insensitive and Arg::multiple_values no longer imply ArgSettings::TakesValue (#2233)
ArgMatches::is_present no longer checks subcommand names
Some env variable values are now considered false for flags, not just "not-present" (clap-rs/clap#2539)
Changed ...s meaning in usage parser. Before, it always meant multiple which is still true for --option [val].... Now [name]... --option [val] results in ArgSettings::MultipleOccurrences.
Usage exit code changed from 1 to 2 (clap-rs/clap#1327)
Reject --foo=bar when takes_value(false) (clap-rs/clap#1543)
No longer accept an arbitrary number of - for long arguments (-----long)

Easier to catch changes:

When using no-default-features, you now have to specify the std feature (reserved for future work)
Gated env support behind env feature flag
- Impacts Arg::env, Arg::env_os, Arg::hide_env_values, ArgSettings::HideEnvValues
- See clap-rs/clap#2694
Gated crate information behind cargo feature flag
- Impacts crate_name!, crate_version!, crate_authors!, crate_description!, app_from_crate!
AppSettings::StrictUtf8 is now default behaviour and asserts if
AppSettings::AllowInvalidUtf8ForExternalSubcommands and
ArgSettings::AllowInvalidUtf8 and ArgMatches::value_of_os aren't used
together
- AppSettings::AllowInvalidUtf8 has been removed
- clap-rs/clap#751
Arg::short and Arg::value_delimiter now take a char instead of a &str
ArgMatches panics on unknown arguments
Removed VersionlessSubcommands, making it the default (see clap-rs/clap#2812)
Completion generation has been split out into clap_complete.
Removed ArgSettings::EmptyValues in favor of ArgSettings::ForbidEmptyValues
Validator signatures have been loosed:
- Arg::validator now takes first argument as Fn(&str) -> Result<O, E: ToString> instead of
  Fn(String) -> Result<(), String>
- Arg::validator_os now takes first argument as Fn(&OsStr) -> Result<O, OsString> instead of
  Fn(&OsStr) -> Result<(), OsString>
Arg::value_name now sets, rather than appends (see clap-rs/clap#2634)
Upgrade yaml-rust from 0.3 to 0.4
Replaced ArgGroup::from(BTreeMap) to ArgGroup::from(yaml)
Replaced ArgMatches::usage with App::generate_usage
Replaced Arg::settings with Arg::setting(Setting1 | Setting2)

Some App functions, like App::write_help now take &mut self instead of &self
Error::message is now private, use Error::to_string
Arg::default_value_if, Arg::default_value_if_os, Arg::default_value_ifs,
Arg::default_value_ifs_os now takes the default value parameter as an option (clap-rs/clap#1406)
Changed App::print_help & App::print_long_help to now return std::io::Result
Changed App::write_help & App::write_long_help to now return std::io::Result
Changed Arg::index, Arg::number_of_values, Arg::min_values, Arg::max_values to taking usize instead of u64
Changed Error::info to type Vec<String> instead of Option<Vec<String>>
Changed ArgMatches::subcommand to now return Option<(&str, &ArgMatches)>
Renamed ErrorKind::MissingArgumentOrSubcommand to ErrorKind::DisplayHelpOnMissingArgumentOrSubcommand
Renamed ErrorKind::HelpDisplayed to ErrorKind::DisplayHelp
Renamed ErrorKind::VersionDisplayed to ErrorKind::DisplayVersion
Added #[non_exhaustive] to clap::{ValueHint, ErrorKind, AppSettings, ArgSettings} (clap-rs/clap#3167)

From structopt 0.3.25

By default, the App isn't initialized with crate information anymore. Now opt-in via #[clap(author)], #[clap(about)], #[clap(version)] (clap-rs/clap#3034)
#[clap(default_value)] is replaced with #[clap(default_value_t)] (clap-rs/clap#1694)
Subcommands nested under subcommands now needs a #[clap(subcommand)] attribute (clap-rs/clap#2587)

Hi @renovate[bot]. Thanks for your PR.

I'm waiting for a ti-community-infra member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
