Since this test requires setup before it can successfully run, we define it as an integration test and move it here so that on a fresh checkout a user can always run `go test ./pkg/...` and expect that it would succeed. Also involves: - Exporting the VersionChecker and adding NewWithConfig to enable testing - Some comment changes - A change to the type returned by New(); see https://github.com/golang/go/wiki/CodeReviewComments#interfaces Ideally I'd not add `NewFromClient` but I think it's the most minimal change and is preferable to publicly exporting `VersionChecker.client`.
