This change allows the admin user to fetch conversation metrics for an account, agents, and filter conversation metrics for a specific agent.
Fixes#4305
This fixes issues in the swagger.json file. The motivation to do so is to be able to generate API clients using https://openapi-generator.tech Doing so will require further changes to the api spec, but this seems like a good first step since it is now "valid" according to editor.swagger.io and openapi-generator validate.
Fixes#2806
- fix the wrong conversation status being sent in webhooks
- additional information in websocket events
- refactor activity messaging code
- move activity message generation to background job to stop the callback loop
