Use network storage for backups

[DennisVredeveld]

Guess this more of a feature request than an issue, so feel free to close if not feasible/possible. It seems that only the local /backup directory is mounted in de docker container. As a result, I can only use this location for backups within DSMR reader. However, HA now supports network storage, which enables users to configure external location as HA backup location. The local backup folder is unused in that case. It would be nice if this network share was also available in the container, so I can use it also for DSMR backups. That way, all backups are at the same location.

Good suggestion, wil definitely have a look when there is the need for a new version.
