[Task] Dockerfile parsing

[taorepoara]

What should be done

Parse the Dockerfile struct from a string.

Technical recommandation

The dockerfile_parser crate can do the job, but it need to be tested in order to see if it can manage all the parameters.

Check if the comments can be parsed two ?

If it does, it might be nice to use for Dockerfile generation two (if the generation format can be the same).

Ecological concerns

Watch the binary size to do grow to much.

Is this task linked with any other ?
