User facing ClusterRoles

ClusterRoleAggregates ToDesription
appscode:stash:editadmin, editAllows edit access to Stash CRDs, intended to be granted within a namespace using a RoleBinding.
appscode:stash:viewviewAllows read-only access to Stash CRDs, intended to be granted within a namespace using a RoleBinding.

These user facing roles supports ClusterRole Aggregation feature in Kubernetes 1.9 or later clusters.
