CLOUDSTACK-6783: Return a proper LibvirtStoragePool object after creating the
pool
In situations where libvirt lost the storage pool the KVM Agent will re-create
the
storage pool in libvirt.
This could be then libvirt is restarted for example.
The object returned internally was missing essential information like the
sourceDir
aka the Ceph pool, the monitor IPs, cephx information and such.
In this case the first operation on this newly created pool would fail. All
operations
afterwards would succeed.

> When libvirt lost the RBD storage pool, could be due to a libvirt restart,
> the KVM Agent will re-create the storage pool.
> When doing so the createStoragePool() method in LibvirtStoragePoolAdapter
> doesn't return a properly filled LibvirtStoragePool object.
> This can lead to situations where the agent for example tries to delete a
> volume, but that fails:
> "Unprotecting and Removing RBD snapshots of image
> null/7a3bdc9f-5cd3-4192-a814-18acf561f0d0 prior to removing the image
> Failed to delete volume: com.cloud.utils.exception.CloudRuntimeException:
> com.ceph.rados.RadosException: Could not set configuration option key (-22)"
> Notice the "null" in the first line, it's because this information is not
> properly filled in the returned object.
