Create Dockerfile

[ebuildy]

Add Dockerfile, image available at:

https://hub.docker.com/r/ebuildy/elasticsearch-tableau-connector/

Run this image:

docker run -p 3000:3000 ebuildy/elasticsearch-tableau-connector

This is a great feature to add to the project. A few items that I think are important to address:

• Can you add a note in the README about running the connector as a container?
• Can you modify the CMD in the Dockerfile to build the connector using the following command:

grunt build:dist

• And then run the connector using:

node index.js

This builds the distribution version of the connector (minifies JS) and runs the web server.

Using grunt will start various development watch tasks that arent necessary for the connector.

Great work!
