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.

Add support for Version 5 XFS filesystems

This includes adding CRC fields to several on-disk
data structures including directory headers, as
well as allowing for a filetype field in the directory
entries.

Rubocop warnings in the code were fixed as well as
style issues pointed out by reviewers.
Raise error when attaching item without dialog to a catalog

I've added a validation function into the ServiceTemplate model, it fixes the bug when editing a catalog item.
The obsolete disabled order button for dialog-less items was removed.
