If HostPID is enabled, this means the Ceph version is older than Octopus
and we are still running OSD with HostPID due to an internal
inter-process check.
If the log collector is enabled we need to enable ShareProcessNamespace
**only** if HostIPC is disabled.
Both HostPID and ShareProcessNamespace cannot be enabled.
