several issues hit while trying to make it easy to register APIs

I was trying to create a script that would register all API versions on a given server and ended up hitting several problems.  These are the fixes.

@sttts I suspect that I won't be able to continue down the host-network approach, since that means I won't be able to use in-cluster DNS without some finagling.  It *could* be set up (and we make it work as a for instance), but the simple enablement approach will be hosted on the infrastructure.  I'll go back to that.
