Subject: [PATCH] Diskmanage: don't run zpool if not present

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).
