remove docker directory add Dockerfile to root directory.

#49 This will build the docker image, some things to note:
This only builds the cli and engine as the UI is being revamped. Once that is done I will look at adding the UI to the image.

You will need to modify /root/odin-config.yml > mongo > address using the command
sed -i 's/localhost:27017/YOUR_MONGO_IP_HERE:MONGO_PORT_HERE/' odin-config.yml

As the yml file is currently like this:
odin: master: "localhost port: "3939" mongo: address: "mongodb://localhost:27017"

Once you have edited it, you can restart the container and the change should be persistent.
