Wrap the -d test with run_or_get_killed sub this test
can make pvestatd hang on I/O wait when a nfsd process is stopped
This might help with other file based storages, for instance
directory storages on unplugged USB devices.
All of them have a `+size` prefix to show that they're not
"pure raw" or "pure tar" streams, because some storage may
need to know in advance how much storage to allocate.
The formats are explained in comments.
PVE::Storage::Plugin now has default implementations for
these for non-incremental streams exporting the current
(rather than a snapshot state).
To use qcow2 or vmdk formats $with_snapshots must be true,
otherwise raw/tar will be used where $with_snapshots must
be false.
So far this only prevented the creation of the toplevel
directory. This does not cover all problem cases,
particularly when said directory is supposed to be a mount
point, including NFS and glusterfs beside ZFS.
The directory based storages we have already use mkpath
whenever they need to create files, and for actions on files
which are supposed to exist it's fine if it errors out.
So it should also be safe to skip the creation of standard
subdirectories in activate_storage().
Additionally NFS and glusterfs storages should also accept
the mkdir option as they otherwise may exhibit similar
issues, eg. when an NFS storage is mounted onto a directory
inside a ZFS subvolume.
vdisk_alloc comes in with an umask of 0037, which means the
.subvol dir has permissions 0740, which means that the root
directory of containers has permissions 0740, essentially
preventing the users inside a container from accessing
anything.
This makes no sense because it should always be exclusive.
Also RDB checks it self.
LVM has not possibility to use lvchange.
DRBD is this feature not implemented.
It is better to check if a VM is running in QemuServer then in Storage.
for the Storage there is no difference if it is running or not.

If snapshot is not reversible catch it before vm will lock and shutdown.
This is the case if zfs has an younger snapshot.

If a plugin overwrites method path() to return optimized setting for qemu,
it can now still use the generic methods from PVE::Storage::Plugin which works
on file system paths (for example the glusterfs plugin).
