[pbs-devel] [PATCH proxmox-backup] close #4763: client: added command to forget backup group

[Gabriel Goller <g.goller@proxmox.com>]

Added the command `proxmox-backup-client group forget <group>` so
that we can forget (delete) whole groups with all the containing
snapshots. As this is quite dangerous, we added a prompt, so the
user has to confirm the operation.
Fixed paths for local dependencies in Cargo.toml.
