Description

This is a placeholder, I have a fix.

A specific deleteStoragePool method attempts to delete a libvirt storage pool, but failures are silently ignored (for example failure to unmount NFS pool because it's in use). Later, when pools are registered, they can fail to register because the mountpoint is in use. Part of my fix is to expose/log failures, and the other part is an attempt to handle the failures.
