This is my first time submitting a patch here, so please let me know if I'm
missing something important, or my email is formatted incorrectly, or anything
else.

This patch adds an option to pass a json configuration file directly into
dockerd for options which aren't available in the docker-configuration record,
of which there are many. From what I've seen, some other packages use a
raw-configuration-string that gets appended into a file to accomplish similar
things, but I figured a file-like was better here because the rest of the
options are passed into the command invocation and not serialized into a file.
