As a User I need the ability to create a test suite so that I can separate my tests in organized manner

Acceptance Criteria
- There should be a user friendly way to define a test suite
- There should be a user friendly way to group scenarios/features under a given test suite
- There should be a way to execute a test suite

No files, tests, or entry points are identified in the issue. Start by surveying the repository to find how scenarios and features are currently defined and executed; done means users can define suites, group scenarios or features under them, and execute a selected suite.
