NetworkPolicy validation improvements
I noticed while implementing NetworkPolicy that I we weren't validating the "Ports" field at all.
The docs are actually completely silent about what a string-valued Port field is supposed to mean. I had guessed it meant to call `net.LookupPort()` on it (ie, map it from /etc/services) but in every other case where we have an IntOrString-valued Port field in an API struct, it refers to a named ContainerPort. But that would be extremely awkward to implement in this case; a policy specifying a named port could end up mapping to a different numeric port on every container in the namespace... Do other people actually implement string-valued ports that way? Or, for that matter, implement string-valued ports at all? (Related: I hadn't noticed until now that you can leave the Port value unspecified, allowing you to say "allow to all UDP ports, but no TCP ports" or "allow to all TCP ports, but no UDP ports". That seems like something that ended up in the spec just because it was possible, not because it was actually useful...)

Improve error message for name/label validation.
Instead of just providing regex in name/label validation error output, we need to add the naming rules of the name/label, which is more end-user readable.
