Switch ScheduledJob controller to use clientset
**What this PR does / why we need it**:
This is part of #25442. I've applied here the same fix I've applied in the manual client in #29187, see the 1st commit for that (@caesarxuchao we've talked about it in #29856).

This means that tags like:
// +foo=bar
// +foo=bat
..will produce []string{"bar", "bat"}. This is needed for later commits which
will want to use this to make code generation more self contained.
Fake clientset is used by unit tests extensively but it has some
shortcomings:
- no filtering on namespace and name: tests that want to test objects in
multiple namespaces end up getting all objects from this clientset,
as it doesn't perform any filtering based on name and namespace;
- updates and deletes don't modify the clientset state, so some tests
can get unexpected results if they modify/delete objects using the
clientset;
- it's possible to insert multiple objects with the same
kind/name/namespace, this leads to confusing behavior, as retrieval is
based on the insertion order, but anchors on the last added object as
long as no more objects are added.
This change changes core.ObjectRetriever implementation to track object
adds, updates and deletes.
Some unit tests were depending on the previous (and somewhat incorrect)
behavior. These are fixed in the following few commits.

[client-gen]Add Patch to clientset
* add the Patch() method to the clientset.
* I have to rename the existing Patch() method of `Event` to PatchWithEventNamespace() to avoid overriding.
* some minor changes to the fake Patch action.

All clients under ClientSet share one RateLimiter.
Currently we create a rate limiter for each client in client set. It makes the reasoning about rate limiting behavior much harder. This PR changes this behavior and now all clients in the set share single rate limiter. Ref. #24157
