the delete parameter get's injected by the SectionConfigs
updateSchem, but we need to handle it ourself in the code
This makes the following possible:
pvesm set STORAGEID --delete property
Also the API equivalent is now possible. Adapted from the HA
managers Resource update API call.

Adds a fallback to 'Plugin::path' in the default implementation of
'map_volume' to simplify a common case of calling 'map_volume' followed
by a defined-check and a call to path if it is not. The path is now
always returned if the plugin in question does not override
'map_volume'.

The underlying issue is that a zpool can get imported only once, so
we first check if it's in `zpool list`, and thus imported, and only
if it does not shows up there we try to import it.
But, this can race with either:
* parallel running activate_storage call, through CLI/API/daemon
* a zpool import from an admin (a bit unlikely, but hey that's the
thing with race conditions ;))
So refactor the "is pool imported" check into a closure, and call it
addditionally if the import failed, and silent the error if the pool
is now listed, and thus imported. This makes it a little bit nicer to
read too, IMO.

Vzdump log files were not deleted when a backup was deleted.
Consequently, the folder continuously filled with .log files.
Now they get deleted after the backup is removed.

Since zfsutils are not a hard dependency of our stack it is possible to not have
`zpool` available.
Checking for existance of `zpool` before calling it suppresses spurious warnings
in the logs (e.g. when creating Ceph OSDs or accessing the 'Disk' Tab in the
GUI).

and datacenter config limit considered)
2) checking that the empty storage list is treated correctly (as with 1).
3) checking that undef can be passed as one element of the storage list (it is
ignored)

during storage activation.
for pools that don't get imported at boot (e.g. because their vdevs are
not available when zfs-import-*.service runs) it is fatal to include
them in the cachefile, for those that do get imported at boot this code
should never run anyway as they are already imported.
in any case, a fallback to import without cachefile is the safe variant.

fixes the 'cannot create 'nvme/foo': volume size must be a multiple of
volume block size' error by always rounding the size up to the next 1M
boundary. this is a workaround until
https://github.com/zfsonlinux/zfs/issues/8541 is solved.
the current manpage says 128k is the maximum blocksize, but a local test
showed that values up to 1M are allowed. it might be possible to
increase it even further (see f1512ee61).

When trying to create a qcow2 disk image with a size larger than available on the
storage, this will fail.
As qemu-img does not clean up the disk afterwards, it needs to be deleted
explicitly. Further, the vmid folder is cleaned up once it is empty.

LVMPlugin->volume_import (used by storage_migrate on either offline
migration with local disks, or online migration with storage-only
referenced disks) passed 'conv=sparse' to `dd`. This can lead to
data-corruption, if the target volume is not zero-initialized.
dropping the sparse argument completely would fix the problem, but
breaks keeping data sparse for LvmThinPlugin.
This patch moves the dd out into (LVM*) plugin specific sub so that
each can control the parameters.
Steps for reproducing the issue:
* create a cluster with (at least) 2 nodes A and B, with a free
disk-device (/dev/sdx)
* write a recognizable pattern to /dev/sdx on B:
`dd if=/dev/zero bs=10M | tr '\000' '\255' | dd of=/dev/sdb bs=10M`
(would be grateful for alternatives to the dd| tr| dd)
* on both A and B create a lvm-vg (pvcreate, vgcreate)
* add it as _not_ shared storage, which is available on nodes A and B
* create a small guest on A
* fill a file in the guest with zeros
`dd if=/dev/zero of=/zerofil bs=10M`
* stop the guest, migrate it to B
* start the guest - check that the file `/zerofil` contains `ad`
instead of `00`

From `man 8 lvchange`:
--refresh
If the logical volume is active, reload its metadata. This is not
necessary in normal operation, but may be useful ... if you're doing
clustering manually without a clustered lock manager.
Fixes migration in a shared LVM (iscsi) setup, where a disk gets resized on one
node A and the guest is afterwards migrated to another node B: B still presents
the old size to the guest, leading to data corruption.
It is necessary to run `lvchange` twice because the options `-ay` and
`--refresh` are mutually exclusive.
