fix: add lock ownership to expire locks (#10571)

- 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.
