* Clean up return value types and docs. * Handle master switch-over better w.r.t the job queue due to binlog name changes (the host portion). Previously the method would fail and trigger read-only mode when waiting on former master positions. Assume the the switch-over was done properly and thus return immediately. Bug: T126436 Change-Id: Ib8c05a5c72d03a5c98e41b23c5653fc194b6d130
