Create Port Range Story

[McCodeman]

• Ricardo to own this issue...

[jayunit100]

• This will be the first, likely easily digestible attempt at a KEP that we serve as one of many, later composable artifacts that this group will create.

Technical considerations

• Can we implement this into the network policy operator stuff as a prototypical implementation?
• Named port groups vs port ranges?

  I've been thinking about this approach, 
  I think it makes more sense in the 'Ports' object, 
  where I want to create a PortSet containing ports 80, 443, 8443,
  call it HTTPPorts and use this instead of a multiport in a network policy

• How many CNIs currently implement this ? (calico, cillim, antrea, openshift-cni, ...)

Will work on this late today.

I would like to review the story and this week (or maximum in the next one, after we review this) create the issue for the kep in the k/enhancements, and the PR for the Kep.

Any thoughts?
