Split internal and external kube-apiserver addresses

[justinsb]

This allows us to select the right IP address when we have multiple
load balancers (one for internal, one for external) as we are planning
to have on GCE.

Renamed to KopsControllerInternal, and also expanded the comments for the enum values (in pkg/wellknownservices/wellknownservices.go)

I'm using "Internal" for in-cluster traffic, and "External" for other traffic. InCluster might be clearer than Internal, but I don't know what a better name would be for External...

WDYT @hakman ... I can probably make #16249 work in a different way, but right now that PR depends on this one (and I think that one is comparatively more important!)

The approach we took in #16379 replaces the need for this (at least that's the belief!)
