[pbs-devel] [PATCH proxmox-backup 2/3] pull: add error context for initial group list call

["Fabian Grünbichler" <f.gruenbichler@proxmox.com>]

otherwise the user is confronted with a generic error like "permission
check failed" with no indication that it refers to a request made to the
remote PBS instance..
