Using t.Run() has some advantages:
- individual sub-tests can be selected with -run
- test failures are automatically associated with
the scenario, therefore the test name no longer
needs to be passed around
A "run" function is used primarily to avoid large indention changes,
but also because this can be used to extend the test with additional
parameters later on.
Add logic in service_controller to skip create/update
if finalizer from a different controller is found.
The newly added finalizer will be checked by other controllers
implementing ILB services to determine if a given service is
already being managed by service_controller.
Moved finalizer check into cloudprovider code.
added unit test to verify new finalizer.
Modified existing unit test to create a fake service so that
attach/remove finalizer step can be tested.
* Move all usage of r.ctx to the beginning of Do, DoRaw, Stream, Watch
* Move tryThrottle from Do and DoRaw into request()
* Make request() and tryThrottle take a context
* In request(), remove the timeout context setting out of the loop
These changes should be entirely behavior preserving.

If a Node name in the cluster is already taken and this Node is Ready,
prevent TLS bootsrap on "kubeadm join" and exit early.
This change requires that a new ClusterRole is granted to the
"system:bootstrappers:kubeadm:default-node-token" group to be
able get Nodes in the cluster. The same group already has access
to obtain objects such as the KubeletConfiguration and kubeadm's
ClusterConfiguration.
The motivation of this change is to prevent undefined behavior
and the potential control-plane breakdown if such a cluster
is racing to have two nodes with the same name for long periods
of time.
The following values are validated in the following precedence
from lower to higher:
- actual hostname
- NodeRegistration.Name (or "--node-name") from JoinConfiguration
- "--hostname-override" passed via kubeletExtraArgs
If the user decides to not let kubeadm know about a custom node name
and to instead override the hostname from a kubelet systemd unit file,
kubeadm will not be able to detect the problem.
