Task:Provide spec for Mer infrastructure on Garage

This proposal arises from the CPH weekend.

It would be useful to have infrastructure for the Mer project on Garage.

This task is not to provide that infrastructure but simply to specify what that infrastructure should support.

Suggestions:
 * Setting up Mer transifex server;
 * bandwidth hungry packaging tasks such as pulling gitorious releases, making packages and pushing to OBS which is unreliable on slow links.
 * Trialing OBS setup
 * Running services such as sprintweb
 * Support the garage/Mer integration work

I am thinking of a number of VMs rather than physical hardware at this point.

This task is not yet ready for consideration :)
