This is but a hack, but we have no general helper/tools module here
and I do not want to do versioned dependencies for this fast-tracked
bugfix to pve-common, so I'll have to live with the shame for now.

We can use 'list_images' to get the desired volume IDs in
'find_free_diskname' for most plugins. For the two LVM plugins, 'list_images'
potentially skips untagged volumes, so we keep the custom version. For the
RBD plugin, 'list_images' is much more costly than the custom version, so we
keep the custom version.

migrate, and are quite scare-mongering. So filter them out.

since 'pvesm export' and 'pvesm import' are connected via a pipe and
SSH, a fatal error in the former can lead to no valid header being
written to the pipe. handle this more gracefully by printing an easier
to understand error message, instead of uninitialized warnings with no
context.

Modern kernel, like 5.3, support all those features ('fast-diff',
'object-map', 'deep-flatten'), so we do not want to disable them
there. 5.0 already supports exclusive-locks, so no need to disable
exclusive locking there.
Further, we also want to profit from new features available, so let's
enable those which can be enabled "live" (i.e., after image creation)
if their available.
While we could also parse the kernel information directly from:
/sys/module/libceph/parameters/supported_features
there's not much advantage to that, features cannot be disabled with
KConfig, their also very dependent of the kernel version booted.
So for us it's enough to check that one.
This only affects container and VMs backed by a storage with KRBD
explicitly enabled. But as the enabling and disabling happens
transparently, it has no effect on the running guest.

The bugfix for #2317 introduced a kind of odd API behavior, where
each volume was returned twice from our API if a storage has both
'rootdir' & 'images' content types enabled. To give the content type
of the volume an actual meaning, it is now inferred from the
associated guest, if there's no guest or we don't have an owner for
that volume we default to 'images'.
At the volume level, there is no option to list volumes based on
content types, since the volumes do not know what type they are
actually used for.

The common ZFSPlugin was missing volume name parsing
in a few places. This was not a problem for standard
volumes, but broke functionnalities (like resize,

(remove base-X-disk-Y prefix)

Using the json output, as suggested by Thomas, we now die if the decoding
fails and, if not, all return values are set to the corresponding decoded
values. That should prevent any unforeseen null size values, except if
qemu-img info reports it, which we then consider as valid.

The patch uses the value from the field 'stored' if it is available.
In Ceph 14.2.2 the storage calculation changed to a per pool basis. This
introduced an additional field 'stored' that holds the amount of data
that has been written to the pool. While the field 'used' now has the
data after replication for the pool.
The new calculation will be used only if all OSDs are running with the
on-disk format introduced by Ceph 14.2.2.

To maintain full (backwards) compatibility, leave the type name as
'iso' - this makes this patch work without changing every consumer of
storage APIs.
Note that currently these files can only be attached as a CDROM/DVD
drive, so USB-only images can be uploaded but might not work in VMs.

checking '$server:$subdir' is too strict to work in all cirumcstances,
e.g. adding/removing a monitor would mean that it is not the same

Since ceph-fuse is called directly in the CephFS storage plugin, which
can not process the _netdev option, mounting the CephFS storage fails
when fuse is set in the storage.cfg.
This patch moves the _netdev option into the else part of the if fuse is
set statement. _netdev is only added if the CephFS kernel client mounts
the storage.
It seems _netdev is not needed anyway for the fuse mount, as the
connection is closed, once the fuse process gets killed on shutdown.
