Enable Health Checks (#1621)

In the release of version 2.0.0 of SCM-Manager, the health checks had been neglected. This makes them visible again in the frontend and adds the ability to trigger them. In addition there are two types of health checks: The "normal" ones, now called "light checks", that are run on startup, and more intense checks run only on request.

As a change to version 1.x, health checks will no longer be persisted for repositories.
