Removing KEPs 2004 and 2030 as they were never implemented

[robscott]

These KEPs were effectively replaced by KEP #2433. Since they never even reached alpha, I don't think there's much of a need to leave them in here.

Fixes #2004
Fixes #2030

For the record, I'm also fine with leaving these KEPs in and updating them to status "replaced". I took the removal approach here because I think it would be confusing to have 4 networking KEPs with "topology" in the name, but not sure what the standard is for removal.

indeed it can be good to have them for historical context

[thockin]

I lean towards removal - they are in the permanent history if we need to get them back.
