[Starcluster] Eucalyptus support

Hi Nicolas,

I've cc'd the list on this one, hope you don't mind.

Before modifying starcluster to connect to Eucalyptus I decided to try it out
manually using ipython shell and boto. I wasn't able to get it to work using
your config settings for some reason, however, I set up my own single-node
eucalyptus cluster today locally and I'm happy to report that boto seems to
work well with my local eucalyptus cluster.

Keep in mind that I haven't done any rigorous testing outside of just playing
around with a few of the boto API calls and there very well may be other
issues lurking. Initial tests seem to indicate that it's possible....we'll
see. I'm adding in configuration support now and will make the necessary
modifications to awsutils.py in the github code so that we can test this out
further.

Stay tuned,

~Justin
