Partitioning StackStorm Sensors #4
Description
See: https://docs.stackstorm.com/reference/sensor_partitioning.html
At the moment st2sensorcontainer K8s configuration consists of Deployment with hardcoded 1 replica and works as a parent responsible to forking/starting/stopping all sensors in the system.
Future plans to re-work this setup (discussion https://github.com/StackStorm/discussions/issues/305) and benefit from Docker-friendly single-sensor-per-container mode (added since st2 v2.9) as a way of Sensor Partitioning, distributing the computing load between many pods and relying on K8s failover/reschedule mechanisms, instead of running everything on 1 single instance of st2sensorcontainer.
Need to codify + config that mode in Docker + K8s Helm templates so user specifies list of sensors he wants to run in values.yaml, Helm takes care about starting a pod for each record.
