notify: add API routes for smtp endpoints

The Perl part of the API methods primarily defines the API schema,
checks for any needed privileges 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.
