[pbs-devel] [PATCH proxmox-backup v2] close #4763: client: added command to forget backup group

[Gabriel Goller]

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.

Note: The dependency to `proxmox-router` needs to be bumped
      to include the change in the other patch.
