Feature Request: annotating rule for spec.matches.labelSelector

[jalseth]

I think this approach makes sense. We will start with matchLabels and we can look into adding support for matchExpressions if that is requested in the future. If you have the time, we'd welcome a PR to add this!

I want to add annotation rules like the following example.

Supporting all representations of labelSelector with annotation rules would be complicated, so I think it is simpler to support only matchLabels.

# @matchlabels app=a team=b
package foo

import data.lib.core
...

↓

apiVersion: constraints.gatekeeper.sh/v1beta1
kind: Foo
metadata:
  name: foo
spec:
  match:
    labelSelector:
      matchLabels:
        app: a
        team: b
