Update CI to fix mounting issues

[katsorio]

Adds

• Adds ${MODELS_ROOT} environment variable that tells where to look for models in bot and web containers.

Changes

• Unifies Dockerfiles for both development, stage and production. Now it's the same image;
• docker-compose.prod.yaml now extends on top docker-compose.yaml used in development;

Fixes

• Fixes mounting issues that can arise in tests by running completely separate test containers

Fixes #227
