RAML support in the app

[jarrodek]

Projects are to become a RAML objects in the app.

The app itself should be able to import RAML file and create a project with endpoints structure.

This step includes only codebase for RAML support. It does not include an UI elements to support RAML.

To be done:

• [x] Database redesign
• [x] Data model for RAML and ARC
• [ ] File import - Parsing and saving results in the datastore, converting it to internal data model
• [ ] Swagger > raml > arc

RAML import and creating is moved to M9.
