Allow setting hpa configuration for sidekiq shards
Similar to !1380 (merged) as more sidekiq shards are brought over to Kubernetes we are finding that the different workloads have different cpu utilization. With different cpu utilization characteristics we would like to have a different hpa configuration per shard.
The hpa configuration is set globally for sidekiq here:
We would like to set this in the pod configuration section, so we can set it per shard:
Adding production request since this is something that came up during the
urgent-other shard migration and will probably need to be completed before we migrate more shards with hpa enabled.
