Align hyperconverged-ceph.yaml environment and adds some validation

Until bug #1635409 is fixed we'll have to keep the default list
of services deployed by hyperconverged-ceph.yaml in sync with the
ServicesDefault list provided in roles_data.yaml

This change adds some logic in the templates validation script to
ensure that is preserved with future updates.

NOTE: the cherry-pick is not clean because two of the services
which are available in the master branch are not available in the
ocata branch, specifically:

- OS::TripleO::Services::Vpp
- OS::TripleO::Services::MySQLClient
