Add debug capable images

[pulkitsinghal]

Summary

Lets add Dockerfile-debug and docker-compose-debug.yml
that can be used when troubleshooting.

Motivation

The images for dolaterio are lightweight and built from scratch which makes it hard to troubleshoot ... maybe we should think of building/publishing debug capable images too?

Given the way the containers are right now ...

$ docker logs dolaterio_api_1
$ docker logs dolaterio_worker_1

gave no output

And attempting to attach to them failed as well:

$ docker exec -t -i dolaterio_api_1 /bin/bash
rpc error: code = 2 desc = oci runtime error: exec failed: exec: "/bin/bash": stat /bin/bash: no such file or directory
$ docker exec -t -i dolaterio_api_1 ls -alrt
rpc error: code = 2 desc = oci runtime error: exec failed: exec: "ls": executable file not found in $PATH
