Use the same reasons for Condition and Event

[tenzen-y]

What this PR does / why we need it:
Currently, jobs use different reasons for Condition and Event even if the situation is the same. (JobCreated vs TFJobCreated)

For example, the JobController uses JobXXX (XXX is the reason such as Failed), and the pytorchjob-controller uses PyTorchJobXXX like this:

training-operator/pkg/controller.v1/common/job.go

Line 227 in fcdf9a3

if err := commonutil.UpdateJobConditions(&jobStatus, apiv1.JobFailed, commonutil.JobFailedReason, failureMessage); err != nil {

training-operator/pkg/controller.v1/pytorch/pytorchjob_controller.go

Line 555 in fcdf9a3

if err := commonutil.UpdateJobConditions(&pytorchjob.Status, kubeflowv1.JobCreated, "PyTorchJobCreated", msg); err != nil {

So I modified the reasons for Condition and Event so that the Jobs use consistently the same reason format ${KIND}${REASON} like PyTorchJobCreated in the same situation.
