/kind hotfix

What this PR does / Why we need it:

Provides the ability to set multiple annotations at once.

This is important if you want an atomic application of the annotations.

Without that, setting annotations is not atomic, so anyone watching for changes required a mechanism to find out when all annotations have been applied. Hard to do if the number of annotation varies.

Which issue(s) this PR fixes:

Closes #3835

Special notes for your reviewer:

Adding some notes in the related ticket around unsetting annotations and labels.
