This removes all .bazel and .bzl files, and a bunch of scripts relating
to bazel, now that it's been entirely replaced.
There are still a few places where traces could be removed, but this
removes the brunt of the bazel stuff that remains.

These tests have external dependencies (rendered CRDs) which mean they
can't pass on a clean checkout without further setup. We define such
tests as integration tests, and so these are moved to test/integration.
