[pbs-devel] [PATCH proxmox-backup v2 08/15] ui: tape: add ChangerStatus panel

[Dominik Csapak <d.csapak@proxmox.com>]

this lets the users manage changers and lets them view the status of one
by having an overview of:
* slots for tapes
* import/export slots
* drives

lets the user:
* barcode-label all the tapes in the library
* move tapes between slots, into/out of drives
* show some basic info when a tape is loaded into a drive
* show the status of a drive
* clean a drive
