[release-1.15] Schduler: MAXFILLUP strategy will spread vreplicas across multiple pods #8290

Conversation

This is an automated cherry-pick of #8263

the MAXFILLUP algorithm was using an affinity strategy, meaning that
it would prioritize adding new vreplicas to pods with the same resources.

However, the downside is that if one pod goes down or gets
re-scheduled the entire resource would be down and not produce
events. By spreading replicas across multiple real replicas we would
guarantee better availability.
