Vedran Pavic fb7e4d6869 INT-4246: Revoke leader when lock isn't acquired ...

JIRA: https://jira.spring.io/browse/INT-4246

The `LockRegistryLeaderInitiator` currently does not revoke leadership
when leading instance is unable to acquire lock from the underlying lock.
This can result in multiple `LockRegistryLeaderInitiator` instances becoming
 leaders in the exceptional situations such as lock timeouts.

* Handle leadership revoking when leading `LockRegistryLeaderInitiator`
is unable to acquire lock
