Researched Mesh Networking

Tonight I have been playing with two new service discoveries that will come to Prometheus:

Kuma: https://kuma.io/ - A service mesh that also runs out of kubernetes

What is interesting is that the Kuma contribution potentially leaves the door open for future envoy/xds-based integrations. The SD also supports long polling, which makes the SD much more efficient.

Uyuni: https://www.uyuni-project.org/ Uyuni is like the foreman but for opensuse. It is not trivial to setup and the endpoint used by the SD is not released yet, but I have received a pretty nice test environment.
