🛠️ Init Configuration checks for clearer feedback

[vpnu]

Summary

When Hutch first runs, it should sanity check (conditionally) required configuration, so that it can give helpful feedback around configuration expectations, instead of allowing misconfigured components to casually throw arcane exceptions.

Starter for 10:

• Is a RabbitMQ connection detailed?
  • can we connect?
• Is a Minio bucket provided if the preconfigured flag is on?
  • can we connect?
• Is a Controller API configured (or the bypass flag is on)?
  • can we connect?
• Is the relevant wfexs config present and correct?
  • e.g. does the working directory exist?
  • is the entrypoint file there?
