    Generate a unique DeployIdentifier on updates

    This patch updates 'overcloud deploy' commands so that
    updates (re-running deploy on an existing stack) generate
    a unique DeployIdentifier parameter. By passing an unique
    DeployIdentifier parameter into the overcloud stack we
    force all puppet config tasks (which are idempotent
    and safe to exec multiple times) again.

    We've had several issues with puppet not-rerunning on
    a variety of config related changes and additionally recieved
    user feedback that not re-running all puppet deployments on
    an update is confusing.
