Add versioning to Magnum Templates

Registered by Jaycen Grant

Add a method to keep track of the current version of a template(Cluster or NodeGroup).

When a template-create is called the version will be set to 1.

An update command will increase the version number by 1. The previous version will be marked as obsolete.

A Cluster/NodeGroup create command that uses a template will always use the latest version available.

A delete Template command will mark the template for deletion. Once no active resources(Cluster/NodeGroups) that reference a template version exist the template versions will be removed from the database.

Template show and list commands will show the latest version only, unless a version is requested on show.

Additional details of this can be found in the following spec: https://review.openstack.org/392327
