> Add ability to get HBase metrics back from an individual request. Apps can use this to
track fine-grained metrics (such as server-side latency, block cache access/hit count; sync
latency; append latency; etc.) on a per-API call basis. Also, enhance HBase shell to support
this feature. [For example, if in the shell we turn profiling on, for all subsequent requests
the profiling stats will be pretty printed, or optionally written to a file.]
