FEATURE: First install scripts

[sheggen]

Rough notes:

Create a config file for managing first install:

• install.sh script that creates the DBs
• read application config to prevent db overwrite
• Implement python's config2 for smarter configuration management across prod/stage/dev

A good config2 example from CELTS app:

• Add code from 12 - 41: https://github.com/BCStudentSoftwareDevTeam/celts/blob/development/app/__init__.py

Progress:

• install.sh created
• database creation automated

Progress:

• uses config2 for different environments

Next steps:

• local auth provider if USE_SHIBBOLETH is 0. (Follow the model used already for USE_TRACY?)
• Start modifying code to leverage APPLICATION FEATURES and LEXICON in default.yaml
• Write into local_overrides.yaml on install these variable: USE_SHIBBOLETH, USE_TRACY, and USE_BANNER
