Eelco Dolstra 4d26546d3c Add support for tracking custom metrics
Builds can now emit metrics that Hydra will store in its database and
render as time series via flot charts. Typical applications are to
keep track of performance indicators, coverage percentages, artifact
sizes, and so on.

For example, a coverage build can emit the coverage percentage as
follows:

  echo "lineCoverage $pct %" > $out/nix-support/hydra-metrics

Graphs of all metrics for a job can be seen at

  http://.../job/<project>/<jobset>/<job>#tabs-charts

Specific metrics are also visible at

  http://.../job/<project>/<jobset>/<job>/metric/<metric>

The latter URL also allows getting the data in JSON format (e.g. via
"curl -H 'Accept: application/json'").
