[pbs-devel] [PATCH proxmox-backup] fix #5233: don't require root for some tape operations

[Dominik Csapak]

instead, require 'Tape.Write' on '/tape' path.
This makes it possible for a TapeAdmin or TapeOperator to
format/remove/vault tapes, instead of just root at pam.

I opted for the path '/tape' since we don't have a dedicated acl
structure for single tapes, just '/tape/pool' (which does not apply
since not all tapes have to have a pool), '/tape/device' (which is
intended for drives/changers) and '/tape/jobs' (which is for jobs only).

Alternatively we could invent a new scheme for tape media, e.g.
'/tape/media' for this.
