Merge lp:~jtv/gwacl/a5-machine-type into lp:gwacl

[Jeroen T. Vermeulen]

Update role sizes: new A5 machine type, and new prices.

Microsoft just sent out an announcement for this new memory-intensive machine type. Neither the email nor the online listings give hard-disk sizes for this new type yet, so I had to give conservative estimates for these. (The listings do show the new type, so this is probably a temporary oversight). I'll file a bug to update those later.

Also note that most of the prices were about half again higher than the ones we had listed. I added a notice pointing out that gwacl is not the last word in Azure's pricing.

Right, I don't think Juju is trying to do billing based on these
numbers. All Juju uses it for is "given the constraints 1GB mem/etc
what is the cheapest thing that fulfills this". Which we only need
relative values for.
We've talked about moving this data into simplestreams actually, so we
can update it without a code rollout, but that isn't today.

Thanks for the review. As you say, we do no billing. The costs are just abstract quantities as far as Juju is concerned. My worry was really that someone using gwacl separately might mistake our costing estimates for authoritative.
