What this PR does / why we need it:

Proposal: Replica of workload gracefully reduction

I propose to introduce a configuration in the PropagationPolicy, so that users can choose the deletion time of Work.

When the Work of some member clusters needs to be deleted, you can configure to delay the deletion operation until all the desired replicas of other clusters are ready.

Thus, avoiding the problem of application out of service.
