Bug#810667: ITP: golang-github-prometheus-common -- Common libraries for Prometheus components

[Martín Ferrari <tincho@debian.org>]

Package: wnpp
Severity: wishlist
Owner: "Martín Ferrari" <tincho@debian.org>

* Package name    : golang-github-prometheus-common
  Version         : 0+git20160104.0a3005b
  Upstream Author : The Prometheus Authors
* URL             : https://github.com/prometheus/common/
* License         : Apache-2.0
  Programming Lang: Go
  Description     : Common libraries for Prometheus components

 * github.com/prometheus/common/log: Wraps https://github.com/Sirupsen/logrus
   in order to add line:file annotations to log lines, as well as to provide
   common command-line flags for Prometheus components using it.
 * github.com/prometheus/common/model: Shared data structures
 * github.com/prometheus/common/expfmt: Decoding and encoding for the exposition format
 * github.com/prometheus/common/route: A routing wrapper around
   https://github.com/julienschmidt/httprouter using `context.Context`

(Note that this package supercedes golang-github-prometheus-log, which I will
ask for removal after all its reverse-deps migrate to this package.)
