    Check whether an HA resource already exists explicitly

    With ephemeral heat we lost the meaning of the 'stack_action' hiera key
    which we previously used to distinguish between fresh deployment and
    pre-existing deployment (aka redeploy).
    Since this hiera key is not available anymore, we simply check if the
    resource existed before running puppet. If it did not, we're part of
    an initial deployment, if it did exist then this is a redeploy and
    in such case, if the config changed we will restart the service on
    the bootstrap node.

    We also cleanup the molecule steps as there are some redundancies there.

    Testing protocol is in the parent change.
