Closes 6937. Allows setting of docker config dir.

Browse source 
Can now dynamically set the docker config directory through an
environment variable.

export DOCKER_CONFIG=/path/to/docker_config/

Default behavior remains the same, e.g. ~/.docker

Documentation for change added to the https.md docs.
