Make memcached port parameters globally available

The memcached_port parameter and the memcached_authtoken_port parameter
are used in each api service. Because memcached and each api services
are not always collocated, we should use global hieradata to ensure
the parameters defined in memcached service resource are propagated to
all nodes in the deployment.
