id ranges: change DNA configuration

Browse Source 
Change the way we specify the id ranges to force uid and gid ranges to always
be the same. Add option to specify a maximum id.

Change DNA configuration to use shared ranges so that masters and replicas can
actually share the same overall range in a safe way.

Configure replicas so that their default range is depleted. This will force
them to fetch a range portion from the master on the first install.
