explicitly specify the cluster and the default resource pool
when importing b/c the import process creates a temporary VM,
which requires a ResourcePool to provision. Same thing when
provisioning a VM.
This is not shipped in RHEL, so use the library directly to query the IP
address. This is a massive hack, but let us revisit this after the next
release.
