Delete deprecated API versions

pkg/service:

There were a couple of references here just as a reminder to change the
behavior of findPort. As of v1beta3, TargetPort was always defaulted, so
we could remove findDefaultPort and related tests.

pkg/apiserver:

The tests were using versioned API codecs for some of their encoding
tests. Necessary API types had to be written and registered with the
fake versioned codecs.

pkg/kubectl:

Some tests were converted to current versions where it made sense.
