[dushimsam]

Signed-off-by: dushimsam dushsam@gmail.com

Description

An endpoint to fetch the list of license candidates.

Changes

1. Added a new controller file and the function to handle the logic in LicenseController.
2. Updated the file AdminLicenseCandidate.php to be reusable by the outside callers.
3. Updated the main file(index.php) by adding a new route GET /license/candidates.
4. Updated the openapi.yaml file to introduce a new API.

How to test

Make a GET request on the end point accessed at "/license/candidates"

@dushimsam , isn't the /repo/api/v1/license?kind=candidate endpoint already provide the required information?

No, i think it's different.
We have Admin License candidates

and Candidate Licenses

So the the API for Candidate licenses already exists which is the one you are showing me.
What I did instead it's to add the other API for Admin License candidates.
