Configure CTF key via enviroment variable

[achimgrimm]

Currently the CTF key will always be used from the key file ctf.key.
While running the shop as a docker container, the file can not be changed.

So there should be the option to set the key via a enviroment variable. This can be passed into the docker container on runtime.

Actually you can mount the file to a file outside the container. See https://docs.docker.com/engine/tutorials/dockervolumes/#mount-a-host-file-as-a-data-volume. Please try that, probably we don't need any implementation for this issue then.

If it works like that it should go into the CTF and customization documentation.

I think this was my suggested solution before:
docker run -d -p 3000:3000 -e "NODE_ENV=ctf" -v /tmp/mySecretKey.key:/juice-shop/ctf.key --name juice-shop bkimminich/juice-shop

I already complted the pull request. So please feel free to merge or decline the PR.
