[Dashboard] Murano dashboard is not available if orchestration service is not available in keystone

[Ekaterina Chernova]

That happens since https://github.com/stackforge/murano-dashboard/blob/master/muranodashboard/dashboard.py#L39

We should soften the permissions and may be show an alert, is heat is not available since murano will not work.
