Description

The ~~HBASE-18070~~ Enable memstore replication for meta replica
turned up follow-ons: tests, doc, guardrails and enhancements. Let me give them their own issue so they do not crowd the original and so I can resolve the original against the version that carries the first implementation of the enhancement (Want to avoid the alternative of an issue that stays open for ever).
