dashboards: add new default frontend route for rendering a dashboard panel

New default route /d-solo/<uid>/<slug of dashboard title> where dashboard
panel are rendered by unique identifier and panel identifier.
If old route /dashboard-solo/db/<slug of dashboard tile> are used,
try to lookup dashboard by slug and redirect to new default route.
Change url logic for sharing a panel so that the new default route
for rendering a dashboard panel are used.
