RFC: lava-server: Remove ZMQ early scheduling trigger
- Unless EVENT_NOTIFICATION setting was enabled (which is disabled by default) listening on ZMQ queue would do nothing as the events would never arrive.
- Scheduler runs every 20 seconds regardless.
- The code was very complex and complicated. The cleaned-up code is much smaller and simpler.
Just-in-time scheduling might be revisited in the future but the current implementation was too clumsy and complicated.
