Support for test headers mining

## Background
The current implementation is missing logic mining information from tests in the repository.

## Feature
- Define the teat header's initial version and the information it will carry.
- Identify the Feature and describe what part of the Feature is covered by a test.
- Add support for data mining of information.
- Add logic to provide this information to the Feature detail page.
- Add logic managing the feature coverage matrix by testing.
- Without test headers, it shows no coverage information.
- Add logic to detect tests in the repository. - Expect strong customization to be available.
- Define the necessary configuration controls that are available to the user.

Note: Make Epic from this issue if needed and provide a solution in smaller parts.
