types.go: Fix CRDKind

[gaocegege]

Close #274

I am not sure why the typo is not reported by our tests.

And, besides this, I found another error after this patch:

ERROR: logging before flag.Parse: I0110 16:52:24.938826    3707 controller.go:117] Starting TfJob controller
ERROR: logging before flag.Parse: I0110 16:52:24.938863    3707 controller.go:120] Waiting for informer caches to sync

Hi @gaocegege. Thanks for your PR.

I'm waiting for a kubernetes or tensorflow member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

What was the behavior that caused an error to be triggered?
Can you file a bug to create a test to cover this?

@jlewi Do you mean the bug #274 or the new error *v1alpha1.TfJobList does not implement the List interface

[jlewi]

I filed #280.
