[bootstrap] Speedup tablet bootstrap
Speedup tablet bootstrap by
- using multi-threads to load tablets metadata
- short circuit return when found an active memory store
in TabletBootstrap::AnalyzeActiveStores()
- improving branch prediction by adding more PREDICT_FALSE/TRUE
on hot path
A simple startup benchmark has been added, it shows that this patch can
reduce about 85% tablets metadata load time.
