Introduce yaml-docker-config python script
Script that takes a FVP yaml file and produces the parameters for a docker-run
command. Conceptually, this is similar to 'pgk-config' system application but
this scripts applies to docker-run parameters.
To exemplify its usage, let's assume we have the a FVP yaml file at ~/fvp.yaml
then launch the container using the script to provide the correct model parameters
$ docker run `./yaml-docker-config ~/fvp.yaml`
If no errors, the (containerized) FVP model should be up and running. In case the
docker image is not found, please create one following the instructions on the
fvp/README.md file.
