Superset version

{"GIT_SHA": "", "version": "0.15.4"}

although there are already some grain control on menus and views, no dashboard-level control and management avaliable for several users.others should not see the dashboard and also its name i built unless i grant it to or share with it? e.g when i entered the welcome page，if i built different dashboards for the same datasource，other users could see it .

### "Dashboard level access control" is really really needed !

Add permissions at the dashboard level.

• Create permissions for each dashboard with the format "dashboard access on dashboard_title"
• The name of the permission is updated if the dashboard title is changed.
• Add a dashboard permission to a role via the Edit Role form, or, for convenience, add a role to a dashboard via the Edit Dashboard form.
• Optionally, add a default role to be added to each new dashboard created from a slice.
• The permission "all_dashboard_access" is added to Admin, Alpha, and Gamma roles.
• To allow private dashboards, remove "all_dashboard_access" from a role. This role will then only have access to the dashboards specified. Add a dashboard's permission to a role to "publish" it.
• Note that these permissions do not apply to slices. To make the data in a dashboard truly private, use dashboard permissions with a read only role that has no slice/explore access.
