[WIP]rubik: supports multi-level priority of CPU and memory QoS · Pull Request !205 · openEuler/rubik

### 描述
1. Configuration changes
Added `volcano.sh/qos-priority` annotation for kubernetes POD, which is used to identify the priority of Pod. The optional values are [`support`, `batch`, `user`, `core`, `system`] (the priority increases in order). If this option is not configured, the default is `user` level.
2. Code optimization:
Implement QoS related methods by defining the operator interface.
3. Function description
Extend the two-level QoS Level to five-level QoS Level. If the volcano.sh/qos-priority and volcano.sh/preemptable annotations are set at the same time, the multi-level priority annotation takes precedence over the two-level priority annotation.
`volcano.sh/preemptable=”true”` is equivalent to `volcano.sh/qos-priority=”batch”`
`volcano.sh/preemptable=”false”` is equivalent to `volcano.sh/qos-priority=”user”`
support, batch are offline services, user, critical, system are online services

>  **system**  (highest level): The process of k8s core components and services, responsible for > maintaining and managing the normal operation of the entire system.
>  **core** : A key component that supports the operation of core business and is crucial to the stability and availability of the business. Such as: payment system, core database, key services (such as authentication, authorization).
>  **user** : The process with which the user interacts directly, providing the user interface and application functionality. Such as graphical interface, browser, etc.
>  **batch** : Mainly handles background batch processing tasks and businesses, such as data processing, transcoding, AI training, etc.
>  **support** : Auxiliary tasks, services or other processes in the system that do not require user participation and require less resources. They may include logging, scheduled tasks, auxiliary services, etc.
