Add horizon checks to maas_local.yml

We're currently only monitoring horizon remotely (via VIP endpoint),
this change creates individual checks so we can identify when
individual horizon nodes go down.

Deploy nova-cert

Currently, we do not deploy nova-cert.  As we do not use the ec2 API
extensively we've not run into any issues however it should exist
for those that choose to use the ec2 API.
Add nova-cert check

This adds a check / alarm to maas_local for nova-cert.  We use the
nova_service_check.py plugin and as long as the nova-cert is running
then we'll have entries in the nova service list output for nova-cert.

Use fixed templates for glance configuration

This change moves away from the template generation to using fixed
template files.  This allows us to conditionally write blocks of
configurations, which I have done for the swift_store options.

This work is largely ripped from @cloudnull's cdc branch.  Note that
there are a few minor configuration changes introduced here by
(from @cloudnull's branch), such as worker count in glance-api.conf.
Glance configuration changes

This change makes notification_driver configurable and only writes
messaging configuration options to glance-api.conf if
notification_driver is set to 'messaging' (it defaults to 'noop').

We also set a default value for 'swift_store_endpoint_type' so that
an ansible run will not bomb if the user does not have
'glance_swift_store_endpoint_type' defined in their user_variables.yml
file.
Required kernel variant check.

Separate out the Cloud Files tenant_id and regular Cloud tenant_id

Cloud Files uses the MossoFS tenant, this is not the same as the

* Separate out the 2 settings in user_variables to ensure these are
  noted as being different values.
