Previously, we introduced a new state to decouple scheduling gated jobs from inqueued jobs and ensure correct computation of inqueued resources without modifying plugins.

We have changed the design of pod scheduling gates. Since the main motivation is to ensure compatibility with K8S, we want to minimize change to existing api and implementations, therefore we no longer make change to the states in scheduler. Instead, we make changes to the plugins to make sure the inqueued resource is calculated correctly when there are scheduling gated tasks. More details in volcano-sh/volcano#3658.
