Description of problem:

This is my customers issue:
I want to control the quota for devspaces user at global level, as of now there is no quota set for a user.
How I can set a quota at global level so that a particular user should not consume all the system resources by defining resources in devfile.
Note: Quota should be at user namespace level controlled by cluster-admin, not at cluster level because it will not solving my purpose.
Please can you review the reproducer below, and advise on the best way to implement CPU and memory controls in workspaces?

Prerequisites (if any, like setup, operators/versions):

Steps to Reproduce

1. Provision ROSA cluster
2. Install devspaces
3. create a cheserver
4. Apply the following RQ to the devspaces workspace namespace:

$ cat resource-quota.yaml
apiVersion: v1
kind: ResourceQuota
metadata:
  name: andbartl-quota
spec:
  hard:
    limits.cpu: "4"
    limits.memory: 5Gi
    persistentvolumeclaims: "4"
    requests.cpu: 3900m
    requests.memory: 4800Mi
    requests.storage: 30Gi

$ oc create -f resource-quota.yaml -n cluster-admin-devspaces 

Now try and add an empty workspace and the following error occurs:

Failed to open the workspace

Error creating DevWorkspace deployment: Detected unrecoverable deployment condition: FailedCreate pods "workspace78e4bff00eea46fb-78db984f76-mkvcn" is forbidden: failed quota: andbartl-quota: must specify limits.cpu for: che-gateway,universal-developer-image; requests.cpu for: universal-developer-image

If I try the same workspace creation with a devfile:

schemaVersion: 2.1.0
metadata:
  name: multi-container-test
components:      
  - name: tools
    container:
      image: registry.redhat.io/devspaces/udi-rhel8@sha256:b0dfd9e15d878785bea5cb33a82a014abbd08c839917e72a8cd629c84bf47f1e
      cpuLimit: 750m
      cpuRequest: 450m
      memoryLimit: 512M
      memoryRequest: 256M
  - name: dixital
    container:
      image: registry.redhat.io/devspaces/udi-rhel8@sha256:b0dfd9e15d878785bea5cb33a82a014abbd08c839917e72a8cd629c84bf47f1e
      cpuLimit: 750m
      cpuRequest: 450m
      memoryLimit: 512M
      memoryRequest: 256M 

and create using my github, I get the following error:

Failed to open the workspace

Error creating DevWorkspace deployment: Detected unrecoverable deployment condition: FailedCreate pods "workspace6b8d5750d44348ce-547969cd78-7dndf" is forbidden: failed quota: andbartl-quota: must specify limits.cpu for: che-gateway
