Not allowed create job if integration is disabled

[stuton]

What happened:
When we apply any job from an integration (JobSet, MPIJob, etc) with a local queue specified in the metadata.labels section and this integration is disabled in the queue controller configuration, we can see the uncontrolled behavior of creating / deleting jobs.

What you expected to happen:
When applying a job with kueue.x-k8s.io/queue-name label, get an error saying that integration is not enabled

How to reproduce it (as minimally and precisely as possible):

1. Deploy Kueue controller manager with default configuration
2. Deploy Jobset controller manager
3. Create local queue
4. Apply one of JobSet examples with defined kueue.x-k8s.io/queue-name label

Anything else we need to know?:

Environment:

• Kubernetes version (use kubectl version):
• Kueue version (use git describe --tags --dirty --always):
• Cloud provider or hardware configuration:
• OS (e.g: cat /etc/os-release):
• Kernel (e.g. uname -a):
• Install tools:
• Others:
