There are environments, like Openstack on Openshift (or CRC) where we
might see two nodes on an environment but one is not acting like a
compute node, thus no VMs can be spawned there. This change checks
specifically for compute nodes and not just nodes on a deployment.
Furthermore, the ALL network log object used to remain in between test
runs because it did not have a cleanup. This is now properly handled.
