[pve-devel] [PATCH v2 many 0/8] notifications: add SMTP endpoint

[Lukas Wagner <l.wagner@proxmox.com>]

This patch series adds support for a new notification endpoint type,
smtp. As the name suggests, this new endpoint allows PVE to talk
to SMTP server directly, without using the system's MTA (postfix).

On the Rust side, these patches add a new dependency to the `lettre`
crate for SMTP communication. This crate was chosen as it is:
  - by far the most popular mailing crate for Rust
  - well maintained
  - has reasonable dependencies
  - has async support, enabling us to asyncify the proxmox-notify
    crate at some point, if needed

These patches are based on top of the `system mail` patch series [1].
From [1], we need the patches for `proxmox` and `proxmox-perl-rs`.
If `pve-docs` from [1] is not applied first, there might be a small conflict,
however that one should be trivial to resolve.

Tested against
  - the gmail SMTP server
  - the posteo SMTP server

Changes since v1:
  - Rebased on top of [1]
  - Added a mechanism for mails forwarded by `proxmox-mail-forward`
    These are forwarded inline as "message/rfc822" to avoid having 
    to rewrite mail headers (otherwise, some SMTP relays might reject the 
    mail, because the `From` header of the forwarded mail does not match the
    mail account)
