Use main events queue in users recognition service

[xtreding]

Problem

On every incoming event, Jitsu writes JSON payload to the separate in-memory queue in (server/users/service.go func Event()). It can lead to increased RAM consumption. It is possible to remove separate users recognition queue and do recognition logic in the main event pipeline - after getting event from the main events queue (server/storages/streaming.go func start()) if a destination is in stream mode or after event deserialization from the batch file (server/logfiles/uploader.go) if a destination in batch mode.

Solution

• [ ] Remove server/users/service.go Event() call from events post processors (server/events pkg)
• [ ] Move (server/users/servoce.go processRecognitionPayload() func) call after enrichment step.
• [ ] Consider that anonymous events will be stored differently according to #724
