[Bug 1871820] [NEW] luminous: bluestore rocksdb max_background_compactions regression in 12.2.13

[James Page]

Public bug reported:

There is a potential regression in the rocksdb
max_background_compactions change in the 12.2.13 point release that is
in bionic-proposed.

https://tracker.ceph.com/issues/44937 was raised as the rocksdb version
in the bionic ceph source does not contain:

  https://github.com/facebook/rocksdb/pull/3926

which ensures that any overlap between background compactions is
detected and handled.

We either need to revert to a single background compaction as the
default setting, or pick the fix into the rocksdb source in
src:ceph/bionic
