Update ureq requirement from 1.4.1 to 2.0.0

[dependabot]

Updates the requirements on ureq to permit the latest version.

Changelog

Sourced from ureq's changelog.

1.5.4

• Fix panic introduced in 1.5.4 on redirects. (#274)

1.5.3

• Backport: follow redirects non-body request on 307/308 (#253)

1.5.2

• Remove 'static constraint on Request.send(), allowing a wider variety of types to be passed. Also eliminate some copying. (#205).
• Allow turning a Response into an Error (#214).
• Update env_logger to 0.8.1 (#195).
• Remove convenience method for CONNECT verb (#177).
• Fix bugs in handling of timeout_read (#197 and #198).

1.5.1

• Use cookie_store crate for correct cookie handling (#169).
• Fix bug in picking wrong host for redirects introduced in 1.5.0 (#180).
• Allow proxy settings on Agent (#178).

1.5.0

• Add pluggable name resolution. Users can now override the IP addresses for hostnames of their choice (#148).
• bugfix: Don't re-pool streams on drop. This would occur if the user called response.into_reader() and dropped the resulting Read before reading all the way to EOF. The result would be a BadStatus error on the next request to the same hostname. This only affected users using an explicit Agent (#160).
• Automatically set Transfer-Encoding: chunked when using send (#86).
• into_reader() now returns impl Read + Send instead of impl Read (#156).
• Add support for log crate (#170).
• Retry broken connections in more cases (should reduce BadStatus errors; #168).

1.4.1

• Use buffer to avoid byte-by-byte parsing result in multiple syscalls.
• Allow pooling multiple connections per host.
• Put version in user agent "ureq/1.4.1".

1.4.0

• Propagate WouldBlock in io:Error for Response::to_json.
• Merge multiple cookies into one header to be spec compliant.
• Allow setting TLSConnector for native-tls.
• Remove brackets against TLS lib when IPv6 addr is used as hostname.
• Include proxy in connection pool keys.
• Stop assuming localhost for URLs without host part.

This should be ready for a review now. The error handling part is still to be discussed at #137, but we can bump the version in the meanwhile.

[ramsayleung]

Why would you like to change the request parameter from &mut to mut?

[marioortizmanero]

ureq's builder pattern no longer uses &mut Request, it's now Request. So instead of using &mut Request and updating the builder with builder.method(), it's now builder = builder.method(), which requires the local request variable to be mutable in the function.
