[Ansible-service-broker] Deployment Templates Backwards Compatibility

> 1. Tag every deployment template to use a specific version of the broker.

Do we have an official support list? I'm concerned with one and only
template, and I don't think we should be supporting much else:

I have the minishift addon to pull this from github, pegged to a tag.
It's hard set to our latest release, and requires manual updates.
It's an explicit desire to have this pegged, but easy to update as we move.
