1. Support per-command PassAfterNonOption …

   Currently, PassAfterNonOption is a Parser flag. This means that it
   applies to all commands. Sometimes it's desirable have this behavior on
   only a subset of commands. For instance, for restart subcommand, we
   would like the default behavior of parsing both -v and --wait flags:
   
     mycmd restart -v foo bar --wait
   
   But for exec subcommand, we want only the -v flag to be parsed. The -l
   flag should be treated as positional argument.
   
     mycmd exec -v ls -l /
   
   Introduce PassAfterNonOption boolean field in Command structure that has
   the same meaning as the flag in Parser but applies only to the currently
   active command. The field can be set by adding pass-after-non-option tag
   to data structure declaration.
   
   This only allows to selectively enable the behavior in commands when
   PassAfterNonOption Parser flag is unset. When the flag is set, the
   behavior is enabled for all commands and cannot be disabled by false
   value of PassAfterNonOption field. This is to keep the code simple and
   backwards compatible (since PassAfterNonOption field defaults to false).
