> Currently, the admission controller is watching all namespaces and tries to
> validate all configmap changes. But we only need to validate the
> yunikorn-related changes.
> Example:
> {noformat}
> $ kubectl logs yunikorn-admission-controller-695869b547-qtfpg
> ...
> 2021-10-04T11:52:19.379Z INFO webhook/webhook.go:83 the admission
> controller started {"port": 9089, "listeningOn": ["/mutate",
> "/validate-conf"]}
> $ kubectl create namespace testnamespace
> namespace/testnamespace created
> $ kubectl create configmap my-config --from-literal=mykey=myval
> --namespace=testnamespace
> configmap/my-config created
> $ kubectl get cm
> NAME DATA AGE
> yunikorn-configs 1 11m
> $ kubectl get cm --namespace=testnamespace
> NAME DATA AGE
> my-config 1 17s
> $ kubectl logs yunikorn-admission-controller-695869b547-qtfpg

> AdmissionReviewResponse {"allowed": true}
> {noformat}

> We need something like the following in {{validations.yaml.template}}:
> {noformat}
> namespaceSelector:
> matchLabels:
> yunikorn
> {noformat}
