"tryserver.chromium.linux" is a full master name, but not full bucket name. A full bucket name is "master.tryserver.chromium.linux"

I think --master should accept master name without "master." prefix. "tryserver.chromium.infra" is a full master name, not to be confused with full bucket name. A full bucket name is "master.tryserver.chromium.infra".

I think we should leave --master for backward compatibility reasons (not prepend "master." prefix) and add -B/--bucket flag that accepts only full bucket name
