private static class EditAccessImpl.ReLockState
Saves state between an unlock from ActivateQueue, and a subsequent re-lock
of the same edit session (if concurrent deployment is enabled, unlock
is called after config changes succeed and reLock will be called if app prepare
subsequently fails. Concurrent deployment guarantees that the same edit session will
not be used in between the unlock and relock, since changes in same partition will not
be allowed to run in that time).
