Remove deprecated replication

[ctubbsii]

This is a work in progress

This would remove a little less than 5% of our lines of code, but would still need follow on work to remove the replication table when upgrading from an earlier version.

All ITs passed with these changes

I didn't see any issues with the changes. LGTM.

This all looks good to me, the only comment I had I made earlier about maybe removing the deprecated methods in Mutation vs the UnsupportedOperationException.

Found another flaky SASL/Kerberos test (ThriftTransportKeyTest) due to JVM reuse, just like in #3074 . Running it in a separate JVM seems to fix it. It's not related to these changes, but needed to isolate it to get it to reliably pass the tests in GitHub Actions. I'm still not sure the underlying actual issue with Hadoop's UserGroupInformation that is causing these, but UserGroupInformation.initializedoesn't seem to like being called twice in the same JVM, and assignment to one particular JVM or another by the surefire plugin seems to be flaky, based on environmental conditions.
