Description

https://github.com/ceph/ceph/pull/4322/files

We accidentally released hammer with a bug where it sets the CRUSH_V4 feature bit whenever a user's CRUSH map has at least 6 bucket types, rather than when they are actually using straw2. The upgrade tests didn't catch this because they use a very small number of CRUSH buckets (#11361), and nothing in the system validate that we ever actually saw the CRUSH_V4 feature.

Implement something so that we can verify features we expect to see enabled in these scenarios.
