introduce a CryptMode enum
...
This also replaces the recently introduced --encryption
parameter on the client with a --crypt-mode parameter.
This can be "none", "encrypt" or "sign-only".
Note that this introduces various changes in the API types
which previously did not take the above distinction into
account properly:
Both `BackupContent` and the manifest's `FileInfo`:
lose `encryption: Option<bool>`
gain `crypt_mode: Option<CryptMode>`
Within the backup manifest itself, the "crypt-mode" property
will always be set.

the files shown have already the '.fidx' or '.blob' file ending, so

s/pbsbanner/proxmox-backup-banner/ + move to /usr/lib
...
We want to avoid pbs if possible and also avoid placing internal
binaries, not intended for human direct use, in /bin or /sbin paths.

add login banner service
...
Modeled after the one from PVE, but using rust instead of perl for
resolving the nodename and writing to /etc/issue
Behavior differs a bit. We write all non-loopback addresses to this
file, as the gui accepts connections from them all, so limiting it to
the first one is not really sensible.
Further an error to resolve, or only getting loopback addresses won't
write out an empty /etc/issue file, but a note about the error at the
place where the address would be displayed.
Named it "pbsbanner", not "proxmox-backup-banner" as it's rather an
internal tool anyway and mirrors pvebanner, pmgbanner
