Siying Dong 3d8ac31d71 Allow users to profile a query and see bottleneck of the query ...

Provide a framework to profile a query in detail to figure out latency bottleneck. Currently, in Get(), Put() and iterators, 2-3 simple timing is used. We can easily add more profile counters to the framework later.
