promote API from v1alpha1 to v1

[grokspawn]

AFTER audits have completed, we should be ready to move the API from v1alpha1 to v1.
Because we are not yet GA, we can move directly and not maintain the older API version.

I will just prep the PRs and put them on hold. We can merge when ready.

I took the couple of minutes that it would take to get it ready, so it's ready for when we need it. Might have been for nought depending on the api review =SS
