mgr/dashboard: 403 Forbidden error with Users with roles cephfs-manager, block-manager or pool-manager
When a user with any mix of the above roles only, tries to access CephFS/Block/Pool pages, he/she receives a 403 Forbidden error ("Sorry, you are not allowed to see what you were looking for").
- Even with Grafana not enabled, all the above roles still try to access /settings/GRAFANA_API_URL, which in turn requires CONFIG_OPT Read permission. When the front-end app tries to reach that endpoint it triggers a 503 in the whole page, blocking the user from any other actions.
