At a high level, each client job will find the correct generator for the request, generate the required configuration, and send it.

#### Optimizations

A naive implementation would simply regenerate all resources, of all subscribed types, for each client, on any configuration change. However, this scales poorly. As a result, we have many levels of optimizations to avoid doing this work.

- When SchedulerQueueingHint is enabled,
  the scheduler's in-tree plugins now subscribe to specific node events to decide whether to requeue Pods.
  This allows the scheduler to handle cluster events faster with less memory.
  
  Specific node events include updates to taints, tolerations or allocatable.

- `EnqueueExtensions` from plugins other than `PreEnqueue`, `PreFilter`, `Filter`, `Reserve` and `Permit` are now ignored.
  It reduces the number of kinds of cluster events the scheduler needs to subscribe/handle. ([#121571](https://github.com/kubernetes/kubernetes/pull/121571), [@sanposhiho](https://github.com/sanposhiho))
