[pmg-devel] [PATCH pmg-gui v2 3/3] add PBSConfig tab to Backup menu

[Stoiko Ivanov <s.ivanov@proxmox.com>]

The PBSConfig panel enables creation/editing/deletion of PBS instances.
Each instance can lists its snapshots and each snapshot can be restored

Inspired by the LDAPConfig panel and PBSEdit from pve-manager.
