Thanks a lot Ishan and Noble for taking this up. This was very much needed for
debugging SolrCloud tests.
There are some additional logging that can be handled here. For example, simple
queries and updates don't log anything other than core name currently. The
SolrDispatchFilter has the core object so it should have all the information
(via CloudDescriptor) to log collection, shard, coreNodeName etc.
I'm re-opening this issue to handle the other stuff instead of creating a new
issue to change un-released functionality.

> In cloud mode, the many log items don't contain the collection name, shard
> name, core name etc. Debugging becomes specially difficult when many
> collections/shards are hosted on the same node.
> The proposed solution adds MDC based stamping of collection, shard, core to
> the thread.
