cephadm: Pin OSDs to pmem modules connected to specific CPUs
I have OSDs running on pmem modules, so i want to pin them to cpus that are connected to those modules. Same with nvmes.
Workaround would be to edit the systemd unit files (or the associated run scripts) for now. (just keep in mind they'll get rewritten, if you redeploy the daemon)
