Move integration tests to molecule (#198)

Move integration tests to molecule

SUMMARY

There are only a handful of integration tests in tests/integration.
These are presumably left over from before the collection used molecule.
The only integration tests that aren't already covered by molecule are
the ones testing kubernetes-validate. I have moved these tests into
molecule so we can delete the integration test job.
