Stop overriding the `GetPodsForJob` of the `JobController`

[tenzen-y]

Currently, all framework-job-controller override the GetPodsForJob of the JobController:

• JobController (is overridden): https://github.com/kubeflow/training-operator/blob/59cc98cbfc906546b096a29f5d31482fba7cdebf/pkg/controller.v1/common/pod.go#L217
• mpijob-controller: https://github.com/kubeflow/training-operator/blob/59cc98cbfc906546b096a29f5d31482fba7cdebf/pkg/controller.v1/mpi/mpijob_controller.go#L508
• mxnetjob-controller: https://github.com/kubeflow/training-operator/blob/59cc98cbfc906546b096a29f5d31482fba7cdebf/pkg/controller.v1/mxnet/mxjob_controller.go#L289
• paddlejob-controller: https://github.com/kubeflow/training-operator/blob/59cc98cbfc906546b096a29f5d31482fba7cdebf/pkg/controller.v1/paddlepaddle/paddlepaddle_controller.go#L284
• pytorchjob-controller: https://github.com/kubeflow/training-operator/blob/59cc98cbfc906546b096a29f5d31482fba7cdebf/pkg/controller.v1/pytorch/pytorchjob_controller.go#L284
• tfjob-controller: https://github.com/kubeflow/training-operator/blob/59cc98cbfc906546b096a29f5d31482fba7cdebf/pkg/controller.v1/tensorflow/tfjob_controller.go#L291
• xgboostjob-controller: https://github.com/kubeflow/training-operator/blob/59cc98cbfc906546b096a29f5d31482fba7cdebf/pkg/controller.v1/xgboost/xgboostjob_controller.go#L294

Maybe, we can commonize the logic and stop overriding the method in all framework-job-controller.
