Tim Hockin a8d83ee1b5 Use Kubernetes declarative validation (#1215)
This mostly eliminates the need to hand-write validation code.

This PR is a long series of commits which add DV for most of Actor and
all of Atespace.

Here is a map to the commits:
* The first few take a dep on a new Kubernetes tag, import the code into
third_party, and apply a single patch. Because we have different Go
modules for tools, I had to do it twice. When that patch lands, we can
revert these commits, but that won't be until the 1.38 cycle in a few
months.
* The next commits slowly add DV support, so a human can review each of
them in a reasonable amount of time. The emphasis is on great test
cases.
* I made a bad choice early on as to where to generate the code into, so
I moved it. Rebasing on that was exceedingly hard, so I left it as a
move.
* This required changing update/go-generate -> update/codegen -- we need
to get the ordering of tools right, which `go generate` does not
guarantee.
* Then I added a "middle" layer called "ServiceImpl" between the RPC and
storage layers. This allows things like workflow to call the same
business logic as the RPC layer, including validation. Lots of test
fixes.
* Then I finished the Create() and Update() paths for Actor. Those
represent the "right" (or closest to) way to implement resources, and
tests for validation.

I strongly encourage reviewers to read it commit-by-commit. Rebasing
this is VERY tedious, so the sooner it lands or dies completely, the
better. Then we can start converting the rest.

`./hack/run-tool.sh validation-gen --docs` will produce some docs on the
tool and the available tags.
