    Description

      Vastly improves HBCK performance. Although we are parallelizing getRegionAssignment() calls, getHRegionConnection()
      gets a big lock. Cache misses can be expensive on heavily-loaded servers because they need to setup a proxy connection. This hurts cache hits on a cache miss & serializes all cache misses. We should parallelize both situations.
