[stable/kube2iam] Rolling updates

[cknowles]

Also bump to latest image version

[k8s-ci-robot]

Hi @c-knowles. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with @k8s-bot 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. I understand the commands that are listed here.

Would it make sense to rather do:

updateStrategy:
  type: {{ .Values.updateStrategy }}

and then set always set it to a value in values.yaml?

@linki yes make sense if k8s adds to the list of values in the future, I will change that now. I think a lot of these sorts of addition would be better in some generic base layer for Helm rather than putting them into every Chart but I think it's the only possibility right now.
