Moxi should automatically skip removed or uninitialized nodes

-Configure Moxi with a list of URL's:
./moxi http://node1:8091/pools/default/bucketsStreaming/default, http://node2:8091/pools/default/bucketsStreaming/default, http://node3:8091/pools/default/bucketsStreaming/default

-Rebalance node 1 out of the cluster (for maintenance)
-Restart Moxi
-Moxi will continuously spin on node1 with the following errors:
2011-04-08 15:30:21: (agent_config.c.389) configuration received
2011-04-08 15:30:21: (agent_config.c.448) ERROR: could not parse JSON from REST server: Requested resource not found.

Two things need to happen here:
-Moxi's logging needs to be improved to tell the user which Node it is connecting to and which ones are giving it problems (not just once at the top, but for every log mesage)
-Moxi needs to realize that this node has an invalid config (it knows it got an error at least) and move onto the next.
