Build out lookup tables

[briri]

The system will need a few tables that contain canned values. These should reside in the RDS instance.

Build the table in RDS and the corresponding scaffolding (Model, Controller, Policy) for each of the following tables:

• tags (contributors (2), costs (7), ethics (3), project_details (1), funding, research_outputs (8), data_preservation (5), security_privacy(4), quality_assurance (6)) This table should include a 'default_order' refer to numbers listed here.
• contributor_roles (use the Credit Taxonomy)
• research_output_types (use the values the DMPTool has defined)
• research_domains (use the WebOfScience values)

Refer to the Define Data Model ticket on the dmsp_aws_prototype repo.

Build RSpec tests for everything!
