    Power off new nodes when making them available, not right after enrolling

    Doing it for newly enrolled nodes that didn't go through "manage" action
    is wrong, because we only validate power credentials during this action.
    Also, this power off request can lock nodes for substantial time, causing
    the following "manage" workflow to fail with "node locked" error.

    Actually, both ironic and ironic-inspector can safely handle nodes that are
    powered on. However, this may be confusing for users looking at node list.

    This patch moves powering off to the "provide" workflow with proper wait
    and error handling.
