Support for OpenSLO format

[paulfantom]

It would be nice to use OpenSLO format to define SLO instead or alongside the current specification.

Yes, for sure. So far I've joined all OpenSLO community meetings and been in touch with folks.
The configuration I have right now was created well before OpenSLO was announced and made public.
I'll need to experiment and figure out how to integrate it with what we currently have 👍

One concern for Pyrra with OpenSLO is that we only support Prometheus and nothing else, so we could be a bit slicker with the config. On the other hand, ignoring non Prometheus configs should work fine just as well.

Seems like a beginning for the solution 😄 OpenSLO/OpenSLO#39
What do you think ? @metalmatze

This one came up at Kubecon (great talk @metalmatze!) quite a few times during Q/A, and the resounding theme was need more contributors! I'm currently working with sig-network (k8s) on a few things or I'd jump on it, but I'm posting this to the OpenSLO and SLOConf slack to see if we can drum up some interest for helping out
