[-] improve Prometheus scrapping, fixes #749 (#790)

First make sure all sinks do not modify measurement envelopes, since
maps in it reference to the same map in memory. Add improved Prometheus
handler in sink, so logs will be populated with all scrapping errors.
Clean cached measurements after each scrape, there is no need in serving
the same data as it will be ignored anyway. Make sure all non-numeric
fields are treated as labels. This will pollute some metrics, e.g.
settings. It's better to rewrite metric queries if the number of labels
is too high.
