## What changes were proposed in this pull request? According to our roles chart a cluster operator should have been able to edit shared widgets. However this was not the case: only Ambari Administrators and Cluster Administrators could do it. I also observed that we did not even use our new RBAC framework (based on `AuthorizationHelper`) in `WidgetResourceProvider`)
## How was this patch tested? Running JUnit tests in `ambari-server`. In addition to this I created users with different roles and tried to edit a widget with the following results: - Ambari administrator - OK - Cluster administrator - OK - Cluster operator - OK - Cluster user - Authorization failure - Service administrator - Authorization failure - Service operator - Authorization failure - None - Authorization failure [ Full content available at: https://github.com/apache/ambari/pull/2274 ] This message was relayed via gitbox.apache.org for [email protected]
