[pve-devel] [PATCH v6 pve-manager 09/30] api: notification: add api routes for sendmail endpoints

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

The Perl part of the API methods primarily defines the API schema,
checks for any needed priviledges and then calls the actual Rust
implementation exposed via perlmod. Any errors returned by the Rust
code are translated into PVE::Exception, so that the API call fails
with the correct HTTP error code.

Notes:
    Changes since v4:
      - Explain the changes a bit more in the commit message
      - Factor out permission checks into a common helper
      - Minor code style improvements
