Michael Stapelberg c1370d07ca Strip trailing / from push URL. 
This circumvents the following problem:
• The prometheus client library appends “/metrics/…” to the pushURL.
• When pushURL ends in a trailing slash, the URL becomes e.g.
  http://pushgateway.example.com:9091//metrics/…
• The pushgateway will reply with an HTTP 307 status code
  (temporary redirect).
• While Go’s net/http client follows redirects by default, it will only
  follow HTTP 302 (Found) and HTTP 303 (See Other) redirects for PUT and
  POST requests, which the prometheus client library uses.

Hence, when calling e.g.:

    prometheus.Push("foo", "bar", "http://pushgateway.example.com:9091/")

…your metrics would not actually get pushed successfully, but rather
you’d see the error message:

    2015/11/26 10:59:49 main.go:209: unexpected status code 307 while pushing to http://push...

William Kennedy f075821cbb Update histogram_test.go 
These tests are always timing out in our Jenkins CI environment. We have moved our timeout to 2 minutes. I have added a check for the short flag so other can skip these tests as we are until this can be identified.

William Kennedy a794f77b54 Update go_collector_test.go 
We are running into a timeout with TestHistogramConcurrency on our Jenkins box. I noticed in the stack trace for the timeout this block.

goroutine 2348 [chan send]:
github.comcast.com/ventris/kober/vnd/github.com/prometheus/client_golang/prometheus.(*goCollector).Collect(0xc20801e8e0, 0xc20800a7e0)

This suggested that even though the TestGoCollector test was finished, a goroutine was still hanging around. I traced it back to the call to c.Collect always sending twice of the provided channel. This change receives that second value and allows the goroutine to finish with the test.

Still can't figure out why TestHistogramConcurrency is timing out after 2 minutes :(

Tomasz Elendt dd4dd69878 Solve "The Proxy Problem" of InstrumentHandler 
InstrumentHandler provides proxy object over given http.ResponseWriter
- responseWriterDelegator that only implements the bare minimum
required of an http.ResponseWriter and doesn’t implement any interface
upgrades (http.Flusher, http.Hijacker, etc.). This commit fixes it by
providing fancyResponseWriterDelegator with all the fancy bells and
whistles if standard library http.ResponseWriter is detected.

Heavily inspired by Goji's middleware.

Tobias Schmidt 765c1152ca Rename process_goroutines to go_goroutines 
The decision was made to use the language name for language specific
metrics, so go_goroutines is the right names similar to
go_gc_duration_seconds.
