State of FMN (FedMSG Notifications) and Replacement

[Clement Verna]

Hi all,

FMN (https://apps.fedoraproject.org/notifications) is currently one of the
main blocking point for dropping fedmsg in favour of fedora-messaging.
FMN is quite important to the community and the composition of Fedora
because it gives emails and notifications on commits, composes, builds and
updates via email and other tools.

However, the code base is written in Python 2.7 and not maintained anymore.
Currently the service has to run on a Fedora 28 system to continue running.
This causes multiple problems and concerns, and needs to be addressed
before the datacenter move in June.

In order to start putting together a specification for a replacement, we
should try to look at the minimum requirements for a notification system.
For example the current system supports sending notifications to IRC,
emails and SSE (Server Sent Event), Can we live without SSE ? Can we live
without IRC ? Do we need it to monitor everything it does currently or just
a subset of items that the community has found useful.

Let's use this thread to brainstorm ideas on what we need.

Thanks all
