* Extend Counters, Summaries and Histograms with creation timestamp

* Backport created timestamp to existing tests

* 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
