Lubomir I. Ivanov 59746fbf4f kubeadm: improve performance of unit tests that need a k8s version ...

The function KubernetesReleaseVersion is being called in
a number of locations during unit tests but by default it
uses a "fetch version from URL" approach.

- Update the function to return a placeholder version
during unit tests.
- Update unit tests for this function.
- Update strings / comments in other version_tests.go
locations.

The improvement is significant:

time go test k8s.io/kubernetes/cmd/kubeadm/app/... -count=1

before:
real    2m47.733s

after:
real    0m10.234s
