fix(kubernetes): Only initialize RoundTripper once

[jchauncey]

fixes #1933

@sparrc Since the kubernetes plugin hadn't been released yet I didnt add this bug fix to the changelog. Do you still want me to do that?

[sparrc]

that's alright, can you rebase your changes so the CircleCI tests pass? Have you tested that this fixes the issue?

[jchauncey]

Yeah we tested that this fixes the issue. I'll rebase in just a bit.

We should probably open an issue to audit the other plugins that reach out over http and make sure they are following the same pattern.
