Proposal: Passing config file

[bompi88]

I would love to be able to mount a local config file and pass the location in with the -c option, something like:

docker run -d
    --link=mongo:mongo
    --link=elasticsearch:elasticsearch
    --volume=/local/path/to/file/.mongoconnector_dev.conf:/mongoconnector.conf
    yeasy/mongo-connector /bin/bash /tmp/startup.sh -c /mongoconnector.conf

[yeasy]

Then u might use the bash -c "blabla" as the docker run cmd.
