Description

Admission controller adds applicationID and label to Pod if they are not already set in the Pod.

According to the new policy defined in YUNIKORN-1351.

Admission Controller will change to patch canonical label/annotation in the future releases.

• yunikorn.apache.org/app-id (Canonical Label)
• yunikorn.apache.org/queue  (Canonical Label)

To avoid an upgrade problem where the admission controller gets started first, AM needs to generate both canonical/non-canonical labels in 1.6.0. (This ensures that the 1.5.0 scheduler could understand labels generated in the 1.6.0 admission controller)  In 1.7.0, we can switch to generating only the canonical label in AM.
