[StarCluster] Action Hooks

[Austin Godber]

Hi Dan,
     Yeah,  I have been playing with them a little bit which is what 
brought up the idea.  The plugins are exactly as you said a post startup 
hook.  If I had a pre-shutdown hook I could save state about the cluster 
prior to shutting it down.  I guess there may not be that many actions 
that need hooking, but I just thought I would throw the idea out there 
so people could give it a think.

     For the most part, I am doing slightly goofy things with 
StarCluster and I don't want to annoy you guys (and Justin) too much.  
But when I think of something that is generally useful I thought I would 
share.  Like the _setup_sge() thing.  I know thats the /main point/ of 
StarCluster, but its also the only line in DefaultClusterSetup that 
makes StarCluster a SGE Cluster creator for EC2 rather than a generic 
cluster creator for EC2.
