Michael Stack resolved HBASE-24164.

Merged to branch-2.3+. Thanks for the patch [~filtertip]. I tried to bring the patch back to branch-2.2 but it would not apply. Mind putting up another PR for 2.2? Can reopen this JIRA or make a sub-issue and ping me for commit. Thanks for the patience.

> When we alter a table, all regions of it will do a rs self move, then the ReadRequests and WriteRequests will be cleared, but they are very useful metrics, my propose is keep them in RegionServerAccounting on close if it is a rs self move, and recover them on open.
