chore(volo-http): refactor client error

[wfly1998]

Motivation

The previous client error is not general enough, and with mod error introduced, rejection error should also be in the mod.

And this PR introduces a new config fail_on_error_status for client. If it is enabled, server response with 4xx or 5xx status will be converted to ClientError with ErrorKind::Status.

In addition, some methods of ClientBuiler are fn foo(self, xxx) -> Self, and some methods are fn bar(&mut self, xxx) -> &mut Self. This PR also unifies them to fn bar(&mut self, xxx) -> &mut Self, because it may be passed to somewhere as &mut ClientBuilder, it is more convenient.

Solution

• Refactor client error from ClientErrorInner to Option<BoxError> and Option<Uri>
• Move RejectionError from server::extract to error::server
• Change most fn foo(self, xxx) -> Self to fn bar(&mut self, xxx) -> &mut Self for ClientBuilder.
