ceph-mgr-modules-core provides a set of ceph-mgr modules which are
always enabeld. but the rook module enables ceph-mgr to install and
configure a Ceph cluster using Rook. this module is very useful but
it does not have such a strong connection with ceph-mgr-modules-core.
we can always install it separately for using better intergration with
Rook.

+* `ceph-mgr-modules-core` debian package does not recommend `ceph-mgr-rook`
+ anymore. As the latter depends on `python3-numpy` which cannot be imported in
+ different Python sub-interpreters multi-times if the version of
+ `python3-numpy` is older than 1.19. Since `apt-get` installs the `Recommends`
+ packages by default, `ceph-mgr-rook` was always installed along with
+ `ceph-mgr` debian package as an indirect dependency. If your workflow depends
+ on this behavior, you might want to install `ceph-mgr-rook` separately.
