ceph: reload API daemons after installation

To make them load the updated librados2, as else they may potentially
not be able to communicate with the potentially newer ceph monitors,
as Debian 10 ships Jewel (12.2) by default...

While we could do some more fancy signaling to the workers to reload
the lib, that is rather a PITA and complex solution for something
that happens once in a blue moon.

We may want to add a trigger in ceph for this on updates though, that
would effectively fix this too - but needs to be thought out better.
So for now lets go with the simplest solution.
