If the ResponseWriter implements any of the following methods,
the ResponseController will call them as appropriate:
Flush()
FlushError() error // alternative Flush returning an error
Hijack() (net.Conn, *bufio.ReadWriter, error)
SetReadDeadline(deadline time.Time) error
SetWriteDeadline(deadline time.Time) error
EnableFullDuplex() error
If the ResponseWriter doesn't implement the methods,
the ResponseController will call Unwrap() method until it
finds a ResponseWriter in the chain
This commit implements Unwrap() method to simply return the
wrapped ResponseWriter

Due to an inconsistency in the text protocol between encoding and
decoding, it was not possible to use the testutil.CollectAndCompare
function to test metrics with empty help values. To fix this, normalize
empty help values from the expected/want side of the test so that they
compare correctly with empty values on the actual/got side of the test.

* Backport created timestamp to existing tests
Signed-off-by: Arthur Silva Sens <arthur.sens@coralogix.com>
* Last touches (readability and consistency)
Changes:
* Comments for "now" are more explicit and not inlined.
* populateMetrics is simpler and bit more efficient without timestamp to time to timestamp conversionts for more common code.
* Test consistency and simplicity - the fewer variables the better.
* Fixed inconsistency for v2 and MetricVec - let's pass opt.now consistently.
* We don't need TestCounterXXXTimestamp - we test CT in many other places already.
* Added more involved test for counter vectors with created timestamp.
* Refactored normalization for simplicity.
* Make histogram, summaries now consistent.
* Simplified histograms CT flow and implemented proper CT on reset.
TODO for next PRs:
* NewConstSummary and NewConstHistogram - ability to specify CTs there.

By upgrading prometheus/client_model, several test functions had to be re-written due to 2 breaking changes made in protobuf when parsing messages to text:
1. '<' and '>' characters were replaced with '{' and '}' respectively.
2. The text format is non-deterministic. More information in https://github.com/golang/protobuf/issues/1121

This commit fixes a data race that exists when the metric used in any
`promhttp` middleware doesn't collect the `code` and `method` but uses
`WithLabelFromCtx` to collect values from context.
The problem happens because when no `code` and `method` tags are
collected, the `labels` function returns a pre-initialized map
`emptyLabels` for every request.
When one or multipe `WithLabelFromCtx` options are configured, the
returned map from the `labels` function call is used to collect the
metrics from context which creates a multi-write data race.

Fixes#1127.
If a native histogram has no observations and a zero threshold of
zero, then it is indistinguishable from a classic histogram. To give
scrapers a hint that it is indeed a native histogram, we add a no-op
span.
This needs follow-up PRs in prometheus/prometheus and
prometheus/client_model.

Switch tests over to new proto libary, eliminating the direct dependency
on the old proto library. Note the indirect requirement is still needed
due to upstream use by the client_model package.
