Description

Background

The MiNiFi C2 Server now supports the C2 protocol, but the /config/heartbeat endpoint is tight to the acceptValue which causes incorrect behavior when using MiNiFi CPP.

Task

We should find a way to serve the /config/heartbeat endpoint with different accept header types than the /config endpoint. Eg.: request heartbeats in JSON and configuration content in YAML (as this is the only supported configuration format atm. by agents)
