close to 2.2;  we've done a version bump for centipede and other dependencies,    also added CreateMachineImage, LaunchInstance, and SSH commands.  a hardcoded instance id is a problem for CreateMachineImage (not harmful so far as I know).  LaunchInstance has hard coded configurations (push out to spring for productionization).  Ssh takes an instance id but it defaults to ubuntu as a username,  that can be fixed by adding a GetOpt.

This all looks easy to fix but I'm going to drop a version now so I can test the effects of the version bump on the whole pipeline.
