Follow up from HBASE-10656, where [~enis] says:

the main problem is that we have A LOT of per-region metrics that are latency histograms. These latency histograms create many many Counter / LongAdder objects. We should get rid of per-region latencies and maybe look at reducing the per-region metric overhead.

Let's consider removing the per-region latency histograms until we have a low impact (in time and space) accounting.
