Support for Oracle

[chriddyp]

This branch demonstrates how to install cx_Oracle on Plotly On-Premise. See Files Changed to see the differences between this configuration and the basic configuration.

Notes:

• System-level packages are installed through apt-get and are specified in the apt-packages file
• The app.json file is used to call scripts while deploying changes.

To run these files on your own machine, you can pull this branch and merge it into your master branch with:

git clone https://github.com/plotly/dash-on-premise-sample-app my-app
cd my-app
git merge oracle  # merges oracle into master

and then you can follow the rest of the instructions in https://plot.ly/dash/deployment/on-premise
