Enable apache-configured-service tempest for keystone

Enable the check jobs for validating keystone under mod_wsgi for
keystone and keystoneclient. This check is enabled for both
(nonvoting) to ensure that a change to keystoneclient does not
introduce issues for keystone under mod_wsgi since keystoneclient
governs the CMS code for PKI tokens.
