@ywk253100
I just created another PR #5283. It is related to this one, and should have confict.
Please take look at it when available.

There is already status.Phase SchedulePhaseEnabled providing similar functionality.
I know the purpose of the phase is used to indicate schedule is validated, but it's still a little confusing, and I think schedule controller's status checking logic needs modification. Maybe some refactoring is also needed.

 		schedule.Status.Phase != velerov1.SchedulePhaseEnabled {


By this condition checking code, if a schedule is marked as FailedValidation, it will not be handled anymore.
To me, this seems not right. Invalid schedule should have a chance for modification.

To me, I think this checking can be put into PeriodicalEnqueueSource fitlerFuncs.
If the schedule is in pending state, no updating should be reasonable.

I also put the generated backup state checking into fitler functions, maybe it should be put into reconcile function, because not handling schedule that has backup in progress could be a surprise for user.

The paused is not set in the test case.

The pause cannot be tested easily in UT after moving the check logic into pridicate, I have remove this line and we'll cover the test in the E2E
