Include keystone authtoken config in manila-share service

Because manila-share is a pacemaker-managed service, it has to be
on the controller node.  If you deploy the api services to a
different node, then manila-share loses access to the authtoken
hieradata generated by manila-api.  Adding it explicitly to the
manila-share config allows this setup to deploy sanely.

Note that I'm having a different problem with manila db-syncs in
this setup, so there's likely another patch required to get it
fully working.
