Error on conversion to unstructured for invalid json.Marshalers.

[benluddy]

If a type's implementation of json.Marshaler returns bytes representing a valid JSON object or array followed by anything other than trailing whitespace, return an error rather than ignoring the trailing data. The documentation for the Marshaler interface indicates that implementations shouldn't do this, but it is safer to check (as json.Marshal does) than to rely on it.

Hi @benluddy. Thanks for your PR.

I'm waiting for a kubernetes-sigs 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.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

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-sigs/prow repository.

/hold

in case you want to call convertNumber for the *interface{} case. I think it would be more uniform und expected. Remove hold at will.
