    Fix auth issue in get_instance_host
    
    _get_instance_host was attempting to use the
    admin username and password with the user's
    tenant, which leads to 401 auth errors from
    Keystone when attempting to determine the
    instance host from nova.
    
    This patch reads the admin tenant from the same
    place as the username and password and uses that
    instead. It also removes the keystone call that
    was used to determine the tenant_id from the name,
    since that is no longer needed.
