[pbs-devel] [PATCH proxmox-backup 4/4] api2/tape/changer: reorganize api

[Dominik Csapak]

add a changer listing here (copied from api2/config/changer)
and put the status and transfer api calls below that

puts the changer scan into the top level tape api
and removes the (now redundant) info from the config api path
