Fix Initial Grizzly HA Module Bugs

::controller

1. Add support for Keystone keystone_token_format and enable_ssl.
Needed to disable SSL and use UUID token format.

2. Added glance_registry_host param. Used to SLB Glance Registry
servers through a VIP.

3. Changed $swift from true to false.  Only 1 controller needs to
create the Keystone Swift auth endpoints.

4. Fixed Cinder's dependency of openstack-ha::db::galera.

::compute

1. Fixed missing comma for tenant_network_type top-level
definition.

2. Removed duplicate enable_ovs_agent definitions.
