Description of problem:

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

login to console with 2 separate users with access to the same namespace

With admin user ensure that each user has the ability to export an app:

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: primer-export
rules:
  - verbs:
      - create
      - delete
      - get
      - list
    apiGroups:
      - primer.gitops.io
    resources:
      - exports

eg Role binding for the `consoledeveloper`

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: consoledeveloper-export-primer
subjects:
  - kind: User
    apiGroup: rbac.authorization.k8s.io
    name: consoledeveloper
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: primer-export

Steps to Reproduce

1. create a namespace
2. create an application (eg deploy openshift/hello-openshift
3. go to topology
4. with user1 export the application
5. with user2 go to the same namespace and attempt to export the application
6. Observe
   user2 cannot export because an export is already in progress
   user2's export may differ from user1 due to differences in rbac
7. wait for user1's export to complete and the toast to appear, do not close the toast
8. with user2 start an export
9. with user1 try to download 
10. Observe
    download fails because starting user2's export results in the deletion of user1's export

Reproducibility (Always/Intermittent/Only Once):

always
