RFC: KEP-4381: DRA: network-attached resources

One-line PR description: nework-attached resources

Other comments:
Adding support for network-attached resources by extending the ResourceSlice with a node selector is fairly easy. The (one!) scheduler in the cluster can use that field during Filter instead of the node name.
Supporting multiple schedulers is harder and needs further work.

When 'Network-attached resources' is said what exactly is the scope of this? Could it be a simple veth case or is this leaning more towards virtual functions?
This PR is not about network hardware in a node. That kind of resource is local to a node and already covered.
What this PR adds is support for things like an IP camera (accessible through the IP network) or special devices that can be accessed through some kind of fabric (GPU via PCI switch). Those resources are not local to a node and therefore need to be handled differently.
