We allow snapshot names that match pve-configid but during qm destroy we have
not removed all snapshots that match pve-configid so far. For example, the name
x-y was allowed but the resulting snap_vm-105-disk-0_x-y was not removed.

This is basically necessary for the GUI's prune widget, because we want to
pass along all options equal to zero when all the number fields are cleared.
And it's more similar to how it's done in PBS now.
Bumped the APIAGE and APIVER, in case some external plugin needs to adapt to
the now less restrictive schema for 'prune-backups'.

First, doing such things can make client work slightly easier, as the
submitted values do not need to be made available in any callback
handling the response.
But the actual reason for doing this now is, that this is a
preparatory step for allowing the user to download/print/.. an
autogenerated PBS client encryption key.

That was lots of code and hash map touching for the case where one
avoided a extra stat, which result probably was in the page cache
anyway, for the case that a backup has a comment.
A case which is rather be unlikely - comments are normally done for
the occasional explicit backup (e.g., before major upgrade, before a
configuration change in that guest, ...), at least not worth some
relatively complicated effort making that sub harder to read and
maintain.

AFAICT the snapshot activation is not necessary for our plugins at the moment,
but it doesn't really hurt and might be relevant in the future or for external
plugins.
Deactivating volumes is up to the caller, because for example, for replication
on a running guest, we obviously don't want to deactivate volumes.

In order to take a snapshot of a container volume, which can be mounted
read-only with RBD, the volume needs to be frozen (fsfreeze (8)) before taking
the snapshot.
This commit adds helpers to determine if the FIFREEZE ioctl needs to be called
for the volume.

This replaces a locally maintained hardware map in
get_wear_leveling_info() by commonly used register names of
smartmontool. Smartmontool maintains a labeled register database that
contains a majority of drives (including versions). The current lookup
produces false estimates, this approach hopefully provides more reliable
data.

Provides recent test data for disk_tests/ssd_smart/sde_smart. The
previous data was created using an older smartmontools version, which
did not yet support the drive and therefore had bogus attribute mapping.

Commit 8fe00d9944 already
introduced the necessary logging for the secure code path,
so presumably the bug was already fixed for most people.
Delay the potential die for the send command to be able to log
the ouput+error from the receive command. Like this we also see e.g.
'volume ... already exists' instead of just 'broken pipe'.

Without this, there are lines like:

already present in more readable form.

we already have the ZFS pool plugin as precedent to use 10s, at for
network with remote off-site storage one can get to 200 - 300ms
RTT latency, which means that for a protocol needing multiple rounds of
communication, one can easily get over 2s while not being in a broken
network.

The LIO backend for ZFS over iSCSI fetches the json-config periodically from
the target.
This patch reduces the stored config values to those which are actually used
and additonally untaints the values read from the remote host's config-file.
Since the LUN index is used in calls to targetcli on the remote host (via
run_command), untainting prevents the call to crash when run with '-T'.
Tested by creating a zfs over iscsi backed VM, starting it, adding disks,
resizing disks, removing disks, creating snapshots, rolling back to a snapshot.

ZFS over iSCSI fetches information about the disk-images via ssh, thus
the obtainted data is tainted (perlsec (1)).
Since pvedaemon runs with '-T' enabled trying to start a VM via GUI/API failed,
while it still worked via `qm` or `pvesh`.
The issue surfaced after commit cb9db10c1a9855cf40ff13e81f9dd97d6a9b2698 in
pve-common ('run_command: improve performance for logging and long lines'),
and results from concatenating the original (tainted) buffer to a variable,
instead of a captured subgroup.
Untainting the value in ZFSPlugin should not cause any regressiosn, since the
other 3 target providers already have a match on '\d+' for retrieving the
lun number.
reported via pve-user [0].
reproduced and tested by setting up a LIO-target (on top of a virtual PVE),
adding it as storage and trying to start a guest (with a disk on the
ZFS over iSCSI storage) with `perl -T /usr/sbin/qm start $vmid`

When creating a new ZFS storage, also instantiate an import-unit for the pool.
This should help mitigate the case where some pools don't get imported during
boot, because they are not listed in an existing zpool.cache file.
This patch needs the corresponding addition of 'zfs-import@.service' in
the zfsonlinux repository.

commit 815df2dd08 introduced a small issue
when activating linked clone volumes - the volname passed contains
basevol/subvol, which needs to be translated to subvol.
using the path method should be a robust way to get the actual path for
activation.
Found and tested by building the package as root (otherwise the zfs
regressiontests are skipped).

Makes it possible to clone and start a container whose
ZFS subvols are not yet mounted for some reason. If a
subvol cannot be mounted, there's a better error now:
zfs error: cannot mount '/myzpool/subvol-103-disk-0': directory is not empty
Previously, cloning would quietly do an "empty" clone,
and startup would fail with:
mount_autodev: 1074 Permission denied - Failed to create "/dev" directory
lxc_setup: 3238 Failed to mount "/dev"
do_start: 1224 Failed to setup container "103"

This is shown in the man page, so it's not important to mention
that this is a wrapper. Also mention the fact that the keep options
from the storage configuration serve as a fallback, which was previously
mentioned in the description of the (now removed) prune-backups parameter.
