feat: parse component TOMLs into docker containers

[merklefruit]

• After #14

Once we have our stack components laid out as TOML files, we will need to parse them into concrete Docker containers in order to start running, orchestrating and monitoring them.

With Bollard, we can use the Docker::create_container() method to prepare a container for a start operation. This requires parsing all image related data along with the rest of the Config.
