feat(serverless-orchestration): local service

[Reinis-FRP]

Motivation

When developing bots it is important to have local test environment that is as close as possible to production. This allows also testing exact cloud configuration locally.

Summary

Adds helper scripts and documentation on how to run serverless orchestration in a local docker service.
