Instead of opening proc/mounts through IO::File directly for parsing,
the patch uses ProcFSTools. This way it also takes care of eventual
decoding.

When destroying an OSD over API or CLI, e.g. by executing:
'pveceph osd destroy <num> --cleanup'
all disks associated with the OSD got wiped with dd, which included
any shared and by others still in use ones, e.g., separate disks with
DB/WAL.
The patch changes 'wipe_disks' to wipe the partition instead of the
whole disk.

It makes more sense to have it there, especially since we want to
split out the service parts into a seperate file.

A MDS gets only active once a FS is there, and we need an MDS active
to be able to add a storage, as the CephFS plugin does an immediate
mount check. As an MDS needs some time to get active we had a
problematic time window where this mounting could fail.
Wait for a MDS to get in active state.

Allow to create a new CephFS instance and allow to list them.
As deletion requires coordination between the active MDS and all
standby MDS next in line this needs a bit more work. One could mark
the MDS cluster down and stop the active, that should work but as
destroying is quite a sensible operation, in production not often
needed I deemed it better to document this only, and leaving API
endpoints for this to the future.
For index/list I slightly transform the result of an RADOS `fs ls`
monitor command, this would allow relative easy display of a CephFS
and it's backing metadata and data pools in a GUI.
While for now it's not enabled by default and marked as experimental,
this API is designed to host multiple CephFS instances - we may not
need this at all, but I did not want to limit us early. And anybody
liking to experiment can use it after the respective ceph.conf
settings.
When encountering errors try to rollback. As we verified at the
beginning that we did not reused pools, destroy the ones which we
created.

Allow to create, list and destroy and Ceph Metadata Server (MDS) over
the API and the CLI `pveceph` tool.
Besides setting up the local systemd service template and the MDS
data directory we also add a reference to the MDS in the ceph.conf
We note the backing host (node) from the respective MDS and set up a
'mds standby for name' = 'pve' so that the PVE created ones are a
single group. If we decide to add integration for rank/path specific
MDS (possible useful for CephFS with quite a bit of load) then this
may help as a starting point.
On create, check early if a reference already exists in ceph.conf and
abort in that case. If we only see existing data directories later
on we abort but do not remove them, they could well be from an older
manual create - where it's possible dangerous to just remove it. Let
the user handle it themself in that case.
