    Wait for node to be unlocked before provide

    This change reduces the risk of provide having a lock timeout by
    waiting for existing node locks to be released before starting the
    provide.

    Ansible based provide may not be affected by bug #1846791 because
    power-down happens after the provide, not before. However waiting for
    locks to be released is recommended practice, and doing it here may
    improve reliability.
