Disable JIT resource creation for project clusters 

JIT resource creation blocks deployments if a user is
self-managing their cluster, as it will fail the build
if unable to create a namespace and service account.

Using a custom namespace and service account was previously
supported for project level clusters, so we should preserve
this functionality.

### Troubleshooting failed deployment jobs
GitLab will create a namespace and service account specifically for your
deployment jobs, immediately before the jobs starts.
deployment jobs. On project level clusters, this happens when the cluster
is created. On group level clusters, resources are created immediately
before the deployment job starts.
However, sometimes GitLab can not create them. In such instances, your job will fail with the message:
