Make sure that argo can manage cluster-wide resources from the releva…

…nt namespaces

Otherwise we can error out with:

  Cluster level ClusterRoleBinding vault-server-binding cannot be managed
  when in namespaced mode

By setting ARGOCD_CLUSTER_CONFIG_NAMESPACES to the namespaces where
argocd instance is installed we allow it to create cluster wide
resources for all namespaces.

Tested this and now I am correctly able to invoke the vault helm chart
from argo without the above error.
