Diskmanage: allow get_disks to take multiple disks

we now expect the first parameter to be either a string with a single
disk, or an array ref with a list of disks

this way we can get the info of multiple disks simultaneously while
not iterating over all disks

this will be used to get the info for osd/db/wal disk
