Most other storage types do not have backup in their default content
selection when creating a new storage, so there it make sense to
initially have maxfiles disabled. But with CephFS we have default
_only_ backup as content type, so let it enabled here - as else one
must change something in the content selector to enable the field.

While we can allow them via the apparmor profile, they still
won't be usable as the kernel doesn't have FS_USERNS_MOUNT
set on those.

Pass the ring addresses from the node we use to join a cluster with
the encoded cluster info. Use it to determine if the nodes public
address (i.e., the onei t's node name resolves to) differs from it'S
ring0 address, if that's the case and the cluster was created with
PVE tooling then we know that it's highly probable that the ring0 is
on another network than the public net, so require the ring0_addrss
field in this case. If we have a false positive, it's not to bad
here.

Allow to specify a separate cluster network when initializing ceph.
Ceph docs[0] imply a possibility for performance increase and
enhanced security in environments where the public network serves not
fully trusted peers, which could else provoke a DOS to the cluster
traffic[0].
Make this optional, but if passed `network` is required too.

Introduce the mdsCount again, I know remember again why I had it in
v3 of my CephFS series.. Use this to disable the CephFS create button
if we have no MDS configured, as this is a requirement.
Further change the gettext for 'No XY configure' to a format string
so that it can be reused.

as we depend on ceph-fuse elsewhere (pve-storage) this gets installed
from Debians repositories with the Ceph 10 version.
So ensure that an up to date version, from our current supported Ceph
release, gets installed when doing `pveceph install` else you may
fall into certain issues which would have been already resolved with
a newer version.

a MDS gets transferred to the active MDS info once it got selected as
active, not once it really _is_ active, it can be there in the
'up:creating' state. So ensure that a MDS with 'u:active' could be
found

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.

We will reuse this in the future, e.g., when creating a data and
metadata pool for CephFS.
Allow to pass a $rados object (to reuse it, as initializing is not
that cheap) but also create it if it's undefined, fro convenience.
