fix(sdk): Fix deprecated client to work with kfp-server-api 2.0.1

[therc]

Description of your changes:

"There are two ways of doing things at Google: the deprecated one, and the one that doesn't work yet" (psrc)

The deprecated client is currently broken, as it refers to APIs that don't exist anymore. This change makes things less broken, but there might be more fixes needed.

We had started by trying to upgrade to the pipelines V2 API, but it's still missing several Kubernetes-specific features that we need (affinities, host mounts, shared memory, etc.). Some have PRs in progress, some not even that.

We then tried using the kfp.deprecated code bundled in V2, because staying on kfp 1.8.5 is preventing us from upgrading several of our Conda dependencies: protobuf, grpc, python-kubernetes, etc. Those, in turn, block other upgrades.

Unfortunately, kfp.deprecated is suffering from bit rot, so some surgery is needed.

Basically:

1. Job -> RecurringRun
2. adapt code from the current client that warns for FOO_job() and forwards to FOO_recurring_run()
3. adapt some code from create_recurring_run()
4. version the APIs we consume: "Api" -> "V2beta1"

Hi @therc. Thanks for your PR.

I'm waiting for a kubeflow member to verify that this patch is reasonable to test. If it is, they should reply with /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.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

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.

This was tested with

kfp                       2.8.0              pyhd8ed1ab_0    conda-forge
kfp-pipeline-spec         0.3.0              pyhd8ed1ab_0    conda-forge
kfp-server-api            2.0.1              pyhd8ed1ab_0    conda-forge

I fixed the YAPF errors, but can't rerun the tests. I guess the failure and/or my new commit made the PR lose its trusted status.

I guess the failure and/or my new commit made the PR lose its trusted status.

that's odd. It's still labeled "ok-to-test", but now it says "10 workflows awaiting approval". @hbelmiro, have you ever seen that before?

@gregsheremeta yes: #10981

[therc]

Had to trigger test-run-all-gcpc-modules again, by hand, but it's all green now. Blocked on approvals. How often are SDKs released? sdk/CONTRIBUTING.md doesn't mention anything about what would trigger a version bump. We'd be happy if it included @gregsheremeta's #10913 as well!

Ping?

I looked it over and it looks fine, but I have 0 experience with v1 or the deprecated stuff ... so ideally @chensun can look at and ack this. I'm inclined to tag it lgtm since it's a deprecated file and the tests pass, but I'll wait for Chen.

We had started by trying to upgrade to the pipelines V2 API, but it's still missing several Kubernetes-specific features that we need (affinities, host mounts, shared memory, etc.). Some have PRs in progress, some not even that.

PRs would be great. We have several example PRs of adding these things back if that would help guide you.

Alternatively, please open issues for the things you need that are still missing.
