Story (Required)

As an Argo-CD administrator, I want the sharding algorithm to automatically scale the number of shards based on workload spikes. The algorithm

Background (Required)

This can be performed by using the horizontalPodAutoscaler (hpa) feature.

Out of scope

Do not try to implement the autoscaling at the controller level, but rather be sure that the application-controller will react properly in case of automatica scaling

Approach (Required)

Enable hpa and see what are the impact. Add the hpa to the operator manifest and add configuration parameter to enable it on user's will.

Dependencies

GITOPSRVCE-613

Acceptance Criteria (Mandatory)

When the CPU load (default hpa) of the pod becomes too high, the hpa should automatically increase the number of replicas of the StatefulSet or the Deployment and the the application-controller should notice it.
