New default route /d/<uid>/<slug of dashboard title> where dashboard
are loaded by unique identifier.
If old route /dashboard/db/<slug of dashboard tile> are used,
try to lookup dashboard by slug and redirect to new default route.
#7883
Since we're already have possibility to get a dashboard by slug
it makes little sense to have a separate endpoint in api for
retrieving uid by slug.
#7883
Introduces new url in api /dashboards/<uid> for fetching dashboard by unique id
Leave the old dashboard by slug url /dashboards/db/<slug> for backward
compatibility and for supporting fallback
