Issue with "Using Docker" in @site/docs/integrations/docker.md

Describe the problem

• Page: Using Docker
• Source: https://github.com/demisto/content-docs/tree/master/docs/integrations/docker.md

A customer would like documentation on the following: 1) Details around the process for loading integration or automation code into the container and executing it. Documentation around how _script_docker_python_loop.py works basically. 2) How containers communicate with XSOAR. The would like to know how data is exchanged and what the format is. For example, how does the xsoar server know when an automation is done running in the container and how does that container pass results back to xsoar.

@glicht , as requested I created this issue to track questions around how we use docker.
