Adding cluster_template and cluster panels for Sahara

The cluster_template and cluster panels give the ability
to define and launch a hadoop cluster (made from
nodegroup_templates).  They are in the same commit because
some of the functionality of cluster_templates requires
that the cluster panel also exist.
