CLOUDSTACK-1846, CLOUDSTACK-1845 - KVM Storage, sometimes KVMHA will remount
deleted NFS pools, causing failures when defining new storage pools. Sometimes
a storage pool has never been used on a host, and getStoragePool fails when
copying templates or in storage migration. deleteStoragePool(pool) often fails
silently, leaving no pool defined in libvirt, but a mountpoint left behind.
This patch handles some of these exceptions and brings forward any issues via
logging.

> 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.
