Description

Now, that the HC api/runtime is available in Felix (FELIX-5952), the system ready checks can be implemented using that.

The attached patch implements the checks DsComponentsCheck, FrameworkStartCheck and ServicesCheck. Since FELIX-6010 it is easy to configure HC servlets that define JSON as default format and return 503 for "non-ready" state.
