chore: start generating REST clients for betas

[codyoss]

tracked elsewhere separately.

LGTM

[quartzmo]

Why did some (but not all) modules need google.golang.org/protobuf added to go.mod?

[quartzmo]

I only reviewed the files for a single client, assuredworkloads/apiv1beta1.

It LGTM.

I'll approve now, but will pull the branch and try to use one of the rest clients against a live service.
