role delete: check for r/o role and role in a group in model

The following (existing) statement in MiqUserRole class:

    has_many :miq_groups, :dependent => :restrict

will prevent from deleting a role in a group, the 'before_destroy'
statement is to prevent a read only role from being deleted.

Therefore, there's no need to be checking for read only role
and a role in a group in the controller code.

group delete: check for a r/o group and group used by users in a model

This fix is:
* to make sure during group removal, the check for a read-only group,
as well as a group still in use by user(s) is being made in the model,
rather than the controller.
* to simplify the (controller) code

Add modeling for template many-to-many tenant

In OpenStack, an image (TemplateOpenstack) can exist in more than one project
(CloudTenantOpenstack).  These migration and model changes allow an OpenStack
template to list the tenants it can be used in, and allows a Cloud Tenant to
list the templates associated with it.

The table is named "cloud_tenants_vms" to reflect the physical tables used in
for the join.

Despite the table name referring to the generic objects, the relationship is
purposefully restricted to Openstack templates and Openstack cloud tenants in
the association defined in the models.  This keeps the notion of the
many-to-many relationship restricted to the most specific level.

The relationship methods are named:

* TemplateOpenstack#cloud_tenants
* CloudTenantOpenstack#opentack_templates

Additionally, to facilitate keeping the relationship as specific as possible,
CloudTenant is now sublassed to CloudTenantOpenstack.  Since all of the existing
cloud tenants are only openstack tenants, the migration initializes all of the
CloudTenant records to have a type of CloudTenantOpenstack.
