The apiserver owns and manages the kubernetes.default service.
It has 3 different options to reconcile the endpoints that belong to
that service:
- None: endpoints are handled by an external party.
- MasterCount: legacy, it reconciles based on the endpoints generated
and a flag specifying the number of master on the cluster.
- Lease: default since 1.11, each apiserver writes a lease in etcd
and renews periodically, the endpoints are generated based on the
existing leases.
It seems that when the default was set for the lease reconciler, the
controlplane code wasn't updated and kept using the master count
reconciler.
This also starts the deprecation of the master count reconciler in
favor of the lease reconciler.
The apiserver may be configured to generate the Service
kubernetes.default and its endpoints addresses.
This service is single-stack, hence, the endpoints and the ClusterIP
must have the same IP family.

use Extraconfig to configure the repair interval
and add an integration test for services finalizers, and
possible races with the services repair loop.
Right now, `_, ok := provider.(Notifier); !ok` can mean one of two
things:
1. The provider does not support notification because the provided
content is static.
2. The implementor of the provider hasn't gotten around to implementing
Notifier yet.
These have very different implications. We should not force consumers of
these interfaces to have to figure out the static of Notifier across
sometimes numerous different implementations. Instead, we should force
implementors to implement Notifier, even if it's a noop.
