Add option: automatically redirect to OAuth IdP

[alwibrm]

In the config section of the OAauth plugin one can activate " Hide login form". As a result there is only the "Log in via oAuth" button left on the TeamCity start page. Since this is the only option left, it would be desirable to redirect the user directly to the OAuth Identity Provider without the need of clicking the button. Even better would be an additional config option, if this should be the preferred behaviour.

Totally agree with @alwibrm :). We've ran into the same thing, where we intentionally disable all other forms, so the button click is really just an additional click.

We would as well be very glad to have such an option. Is this something that is doable? We would greatly appreciate it.
