kubeadm/join: expose the KubeConfigPath() method to joinData

Clear EndpointsLastChangeTriggerTime when there is no new trigger time to be exported

e2e/storage: delay CreateDriver, simplify APIs and test definition

This fixes the following error:
"error execution phase control-plane-join/etcd:
control-plane-join phase invoked with an invalid data struct"

The problem here is that joinData cannot be type-asserted
to the interface type under controlplanejoin.go (controlPlaneJoinData)
because joinData lacks KubeConfigPath.

Given we use KubeConfigPath in more than one place for join
it makes sense to define define the method and make it return:
kubeadmconstants.GetAdminKubeConfigPath()

kubectl: fix a bug where "describe" cannot obtain the event messages for a static pod

We should clean the EndpointsLastChangeTriggerTime annotation when there
is no new trigger time to be exported. Not clearing it may result in
kube-proxy exporting the wrong Network Programming Latency SLI.
