When loadbalancer_apiserver_localhost is enabled, Calico falls back to the
Kubernetes service IP because the kubernetes-services-endpoint ConfigMap is
empty. CNI then fails to reach the API server even though an nginx proxy is
listening on localhost.
Update kube_apiserver_global_endpoint to always reference the localhost load
balancer (respecting the configured port) and populate the ConfigMap for both
eBPF and localhost LB modes.
This commit removes the variable `use_localhost_as_kubeapi_loadbalancer`
and rather detects that we are in a situation where we can use the
localhost apiserver loadbalancer (meaning that we use the localhost load
balancer and that the same ports are used for both the load balancer and
the kube-apiserver).
This also cleanups the calico code to use `kube_apiserver_global_endpoint`
rather than implementing the same logic all over again.
