Bug Description
As in the title, if machine has multipath storage device connected e.g. JBOD via SAS controller, then each disk in the JBOD is reported N times, depend how many paths you have. It's problematic when you do commissioning as things are done multiple times, badblock test takes forever as each disk is done multiple times and also configuring when you do e.g. Ceph OSD deployment as you don't see a device you are going to use, you have to first ssh into a system and check all /dev/mapper to find a correct device for OSD.

MAAS does not currently support multipath devices. Curtin, the tool MAAS uses to perform installations, does. We'd have to add support for gathering information on multipath devices during commissioning, a way to properly configure multipath storage, and a way to test multipath devices.
