Update the database using an online replication service.

+ An OSM replication service is an online service that provides regular
+ updates (OSM diff files) for the planet or update they provide. The OSMF
+ provides the primary replication service for the full planet at
+ https://planet.osm.org/replication/ but there are other providers of
+ extracts of OSM data who provide such a service as well.
+
+ This sub-command allows to set up such a replication service and download
+ and import updates at regular intervals. You need to call '--init' once to
+ set up the process or whenever you change the replication configuration
+ parameters. Without any arguments, the sub-command will go into a loop and
+ continuously apply updates as they become available. Giving `--once` just
+ downloads and imports the next batch of updates.
