fix: namespace-scoped mode by service_controller

[Jooho]

Add a ClusterScope condition statement to list namespace that is only allowed for cluster scope.

Resolves #433

[Jooho]

Test image:

• quay.io/jooholee/modelmesh-controller:v0.11.1

With the test image, FVT test passed locally.

Test Steps:

git clone git@github.com:kserve/modelmesh-serving.git
cd modelmesh-serving

minikube start --kubernetes-version=1.26.1 --memory=30G --cpus=8  --disk-size=100g
kubectl create ns modelmesh-serving

CONTROLLERNAMESPACE=modelmesh-serving NAMESPACE=modelmesh-serving MODELMESH_SERVING_IMAGE=quay.io/jooholee/modelmesh-controller:v0.11.1 NAMESPACE_SCOPE_MODE=true make deploy-release-fvt

NAMESPACE=modelmesh-serving CONTROLLERNAMESPACE=modelmesh-serving NAMESPACESCOPEMODE=true make fvt

It will fail until the required images are downloaded. but it will pass all fvt tests eventually.

@ckadner FVT test passed on local minikube. I think it should work with gitaction eventually. could you please trigger the fvt test? I think I can not retrigger the gitaction.

Thanks @Jooho for providing a fix quickly!
