First version of cluster web service....
First version of cluster web service. This exposes ipcluster's over the web. The current implementation uses IPClusterLauncher to run ipcluster in a separate process. Here is the URL scheme we are using: GET /clusters => list available clusters GET /cluster/profile => list info for cluster with profile POST /cluster/profile/start => start a cluster POST /cluster/profile/stop => stop a cluster
