PDB-554 Switch to using new experimental ec2 beaker driver

This patch modifies our Gemfile and acceptance configuration so that we are
using my experimental EC2 backend driver from beaker.

At the moment its just pointing at my branch, so we can continue to test this
with our real Jenkins runs before releasing it to beaker proper.
