SOLR-5399: Add distributed request tracking information to DebugComponent

> I'm working on extending the DebugComponent for adding some useful
> information to be able to track distributed requests better. I'm adding two
> different things, first, the request can generate a "request ID" that will be
> printed in the logs for the main query and all the different internal
> requests to the different shards. This should make it easier to find the
> different parts of a single user request in the logs. It would also add the
> "purpose" of each internal request to the logs, like:
> RequestPurpose=GET_FIELDS,GET_DEBUG or RequestPurpose=GET_TOP_IDS.
> Also, I'm adding a "track" section to the debug info where to add information
> about the different phases of the distributed request (right now, I'm only
> including QTime, but could eventually include more information) like:
> {code:xml}
> <lst name="debug">
> <lst name="track">
> <lst name="EXECUTE_QUERY">
> <str name="localhost:8985/solr">QTime: 10</str>
> <str name="localhost:8984/solr">QTime: 25</str>
> </lst>
> <lst name="GET_FIELDS">
> <str name="localhost:8985/solr">QTime: 1</str>
> </lst>
> </lst>
> </lst>
> {code}
> To get this, debugQuery must be set to true, or debug must include
> "debug=track". This information is only added to distributed requests. I
> would like to get feedback on this.
