Merge lp:~rvb/maas-test/better-create into lp:maas-test

[Raphaël Badin]

Add options to improve the performance of the VM.

--unsafe-caching improves significantly the performance of the VM, especially when running on a KVM machine. It's safe to use that for us, especially since our instances are short-lived, disposable machines.
--disk 20 (the default is 8) is just to make sure we have enough room. The disk is not pre-allocated so there is no cost in doing that.
--memory 2048, well, this also significantly improves the performance of the VM
