Support a federated Prometheus setup

Gerrit instances that are loadbalanced cannot easily e scraped by
an external Prometheus, since the request won't end up at a specified
Gerrit instance. A typical setup to solve this issue, is to install a
local Prometheus and scrape the local Prometheus from the central
Prometheus. This is a so called federated setup.

Now such a setup is supported and can be configured.
