Log caching of shards in the query

[GoogleCodeExporter]

Reported by [email protected]

Currently cache is only logged for the initial or base URL for the test. When 
adding multiple shards to the query the cache information only pertains to the 
base URL and ignores the cache stats of the shard cores.

I think individual monitoring as opposed to aggregated statistics will make the 
most sense. That way you can pick individual shards in the GUI and compare 
differences in hit rates, evictions, etc.
