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.
