* Extend Counters, Summaries and Histograms with creation timestamp
Signed-off-by: Arthur Silva Sens <arthur.sens@coralogix.com>
* 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

This replaces usage of proto.{Float64,Int32,Int64,String,Uint32,Uint64},
which doesn't break the interface.
And remove usage of proto.MarshalTextString in wrap_test.go

`github.com/golang/protobuf/proto` is deprecated in lieu of
`google.golang.org/protobuf/proto`. However, we cannot simply
migrate. Types from the proto package are exposed to users of packages
in this repo. If we migrate here, users have to migrate to. Thus, we
could only migrate with a major version bump.
In different news, with all the inline lint:ignore comments, including
the existing ones, there is no need to repeat the exception in the
Makefile.
A current version of `staticcheck` is happy with the code after this
commit. golangci-lint is broken at the moment, however, and ignores
the lint:ignore comments in the code as well as those via envvar.
