- Add owner information for expiry, locking, unlocking a resource - TopLocks returns now locks in quorum by default, provides a way to capture stale locks as well with `?stale=true` - Simplify the quorum handling for locks to avoid from storage class, because there were challenges to make it consistent across all situations. - And other tiny simplifications to reset locks.
