Rook mgr module crashes due to missing mgr.nfs

Bug description:
[Impact]
The rook mgr service crashes on installing the ceph-mgr-rook package
(see below traceback from /var/log/syslog). This is due to a missing
ceph mgr package "nfs" which the rook mgr module depends upon.
This makes the rook mgr module unusable which is required for
integrating Ceph with the Rook storage orchestrator.
The proposed patch fixes this by including the nfs mgr package into
the ceph-mgr-modules-core .deb. This is similar as upstream packages
nfs for the ceph mgr system.

[Test plan]
The test requires a Ceph cluster. SSH to a system with a running ceph-
mon service.
$ sudo ceph mgr module ls # verify: no rook mgr module
$ sudo apt-get -q install ceph-mgr-rook
$ sudo ceph -s # verify: no crashed modules
$ sudo ceph mgr module ls # verify: rook mgr module present and enabled
[Where problems could occur]
The proposed patch only includes an additional Python package, and
regression potential should be low.
Issues could occur due to packaging bugs, such as missing dependencies
for the nfs mgr package. As the nfs package is currently missing,
there should not be any additional impact due to this.
