Clean up the whole of training-operator

[tenzen-y]

After merging kubeflow/common into this repo, we have many redundant and duplicated codes in this repo.
So, we should clean up the whole of this repo.

• Replace dummy client with fake client: Replace dummy client with fake client #1818
• Remove TestJobController: Refactoring tests in common/controller.v1 #1843
• Organizing utils: Clean up /pkg/common/util/v1 #1845
• Remove Reconciler: Removing reconciler code #1879
• Completely remove test_job:

/kind cleanup

ref: #1813

As utils are cleaned up, Is there something pending in this issue?

@johnugeorge I think we need to decide how we handle the reconciler because the reconciler is dead codes.

@johnugeorge I think we need to decide how we handle the reconciler because the reconciler is dead codes.

I think we can just remove the reconciler part.

@zw0610 This part aim to give a unified controller implementation which do not depend on specific kind of job, am I right ?
If so, the next version of real UNIFIED training operator would profit it.

[tenzen-y]

which do not depend on specific kind of job

@kuizhiqing Currently, this is the responsibility of the controller. The reconciler provides functionality the similar to the controller using the concept inspired by controller-runtime.

Although the reconciler's idea is much great, the reconciler is no longer maintained, a dead code.

So I would suggest removing the reconciler.
In the future, maybe we can implement common codes in a more controller-runtime native form.

I added the last task, Completely remove test_job, to this issue description.

@tenzen-y I think are aligned in this topic. I developed operators with controller-runtime heavily, so I think we do not fully take the advantage of it here. And I am agree with you that,

• we should remove reconciler here
• in the future we may introduce it with more native way

Yes, that's right. Thanks for being aligned.
