Add caching information to RDD.toDebugString
I find it useful to see where in an RDD's DAG data is cached, so I figured
others might too.
I've added both the caching level, and the actual memory state of the RDD.
Some of this is redundant with the web UI (notably the actual memory
state), but (a) that is temporary, and (b) putting it in the DAG tree shows
some context that can help a lot.
