Automatic merge from submit-queue (batch tested with PRs 40932, 41896, 41815, 41309, 41628)

Modify CronJob API to add job history limits, cleanup jobs in controller

**What this PR does / why we need it**:
As discussed in #34710: this adds two limits to `CronJobSpec`, to limit the number of finished jobs created by a CronJob to keep.

**Which issue this PR fixes**: fixes #34710

**Special notes for your reviewer**:

cc @soltysh, please have a look and let me know what you think -- I'll then add end to end testing and update the doc in a separate commit. What is the timeline to get this into 1.6?

The plan:

- [x] API changes
  - [x] Changing versioned APIs
    - [x] `types.go`
    - [x] `defaults.go` (nothing to do)
    - [x] `conversion.go` (nothing to do?)
    - [x] `conversion_test.go` (nothing to do?)
  - [x] Changing the internal structure
    - [x] `types.go`
    - [x] `validation.go`
    - [x] `validation_test.go`
  - [x] Edit version conversions
    - [x] Edit (nothing to do?)
    - [x] Run `hack/update-codegen.sh`
  - [x] Generate protobuf objects
    - [x] Run `hack/update-generated-protobuf.sh`
  - [x] Generate json (un)marshaling code
    - [x] Run `hack/update-codecgen.sh`
  - [x] Update fuzzer
- [x] Actual logic
- [x] Unit tests
- [x] End to end tests
- [x] Documentation changes and API specs update in separate commit


**Release note**:

```release-note
Add configurable limits to CronJob resource to specify how many successful and failed jobs are preserved.
