[Umbrella] Multi-components workload scheduling - phase ​​IV #7492

Summary:

This issue is used to track the iteration tasks of feature Multi-components workload scheduling described at #5115.
See proposal for more details.

**Iteration Tasks:

• Support multi-template application scale scenarios
  • Ensure multi-template applications have the opportunity to enter the rescheduling process.
  • During rescheduling, replica set estimation should take scheduled components into account.
    • For scale-up, only the incremental components/replicas need to be considered.
    • For scale-down, replica set estimation could be skipped.
  • If rescheduling fails, ensure the updated configuration is not propagated to member clusters.
