DOMAIN SHARDING
---------------
Chrome allows up to 6 open connections per domain at a time. When there are more
than 6 slices in dashboard, a lot of time fetch requests are queued up and wait for

and this feature will be enabled by configuration only (by default Superset
doesn't allow cross-domain request).
