[pve-devel] [RFC proxmox-backup/storage/zfsonlinux] improve zpool import for freshly created zpools

The issue of created zpools not being imported on boot, due to a
missing/partial/corrupt zpool.cache file is something which we see quite often
reported in our various support-channels.

With PVE the issue was mitigated (and it did not show up so often), since
pvestatd does activate all storages (which imports all referenced zpools).

This does not hold for proxmox-backup (see the thread in our community forum
[0]).

After a short off-list discussion with Fabian (G.) the following patchset
addresses the issue by adding 'zpool-import at .service' to our zfsonlinux repo
and instantiating the template unit in the API paths where we create
zpools (for storages or datastores)

quickly tested on testsetups of mine (by adding a pool and then checking
when it got imported according to the journal).
