[FEATURE] Limit Ranges

[tekno45]

I want to be able to set LimitRanges on all my namespaces. but there is no mechanism for a clusterwide LimitRange.|

If this could be replicated across namespaces it would solve my use-case.

kind: LimitRange
metadata:
  name: mem-limit-range
spec:
  limits:
  - default:
      memory: 512Mi
    defaultRequest:
      memory: 256Mi
    type: Container
    ```
    
    
    Like this but for all namespaces is what im looking for.
