Prometheus support

Hi Remi.

Curious what the rationale is for removing Prometheus support: ad8a2f1

At the time, Prometheus 1.0 kinda sucked and the code in optics was very problematic to maintain so I removed it as it wasn't used.

That being said, Prometheus 2.0 had addressed most of my original problems and we're looking to migrate to it this year. @contested-space will be looking into it in the coming months.

Out of curiosity, do you need it or is this general curiosity? I can probably accelerate the process if necessary.

Just general curiosity - thanks. Too bad the Prometheus doesn't maintain an official c client.
