    Block endpoint reg if cluster partially formed

    When an existing cluster of the service is scaled out the new unit
    will join with keystone before it is fully clustered. In identity
    joined hook the charmhelpers function canonical_url is called which
    in turn uses another charmhelpers function, resolve_address.
    resolve_address will only return the vip if the vip is set in config
    AND the unit is clustered. This means that the units local address
    is returned and that is then registered with keystone.

    This change gates registering an endpoint if the cluster is
    partially formed.
