Stop using deprecated Gerrit REST API.

* Suppress console warning messages about
  deprecated REST API and onAction.
  * The Gerrit REST api were deprecated for more than a year in
    https://gerrit-review.googlesource.com/c/gerrit/+/137131
  * Replace Gerrit.get() with self.restApi().get(),
    and the same for post() and delete().
  * No longer support old obsolete GWT UI.
* Explicitly use upper case for the [FIND OWNERS] action label.
* Catch and pop up alert message when a reviewer cannot
  be deleted. This happens when the action is invoked
  by someone not the owner of a CL.
