Description

Once we've resolved our feature flags situation (see CASSANDRA-18195) and in-flight work (see CASSANDRA-18192) we want before merge, here is the rough plan for getting cep-15-accord merged to trunk:

1.) Run cep-15-accord pre-squash against CircleCI to establish a baseline.
2.) Squash ninja commits out of cep-15-accord and rerun tests pre-rebase.
2.) Rebase cep-15-accord to trunk and rerun tests.
4.) Merge cep-15-accord to trunk if tests are clean and there are no public objections.
