If pulumi operator pod/leader is restarted by any reason it may not remove lock for a stack. As a result next leader can not work with the locked stack. It makes operator unstable.

error: could not create stack: the stack is currently locked by 1 lock(s). Either wait for the other process(es) to end or delete the lock file with `pulumi cancel`.
