Limiting number of concurrent traces API requests for the local stack… (#236)

* Limiting number of concurrent traces API requests for the local stack to avoid occasional OOM-s

* Limiting number of verticles for Traces API node

* Trying out Besu untuned and raising limit per endpoint to 2 for traces

* Trying out Besu untuned and raising limit per endpoint to 2 for traces and Shomei node

* Using besu untuned for arithmetization as well
