Endpoint to paginate through all repos

[bradrydzewski]

We should have an /api/repos that allows a system administrator to paginate through the full list of enabled repositories in the system.

[bradrydzewski]

added /api/repos endpoint which is limited to system administrators at this time. It returns a paginated list of all repositories in the database, including disabled repositories.

GET /api/repos
GET /api/repos?page=2&per_page=100

since this endpoint is restricted we do not enforce a maximum page size. you can therefore dump all repositories in the system in the response, however, please be consider performance and resource consumption when doing so. Also, we may choose to limit per_page to 100 maximum results in the future.

GET /api/repos?page=1&per_page=5000
