beorn7 31318b7523 Switch to base-2 buckets
This seem what OTel is converging towards, see
https://github.com/open-telemetry/oteps/pull/149 .

I see pros and cons with base-10 vs base-2. They are discussed in
detail in that OTel PR, and the gist of the discussion is pretty much
in line with my design doc. Since the balance is easy to tip here, I
think we should go with base-2 if OTel picks base-2. This also seems
to be in agreement with several proprietary solution (see again the
discussion on that OTel PR.)

The idea to make the number of buckets per power of 2 (or formerly 10)
a power of 2 itself was also sketched out in the design doc
already. It guarantees mergeability of different resolutions. I was
undecided between making it a recommendation or mandatory. Now I think
it should be mandatory as it has the additional benefit of playing
well with OTel's plans.

This commit also addresses a number of outstanding TODOs.

beorn7 f34b09877c Pull out ...WithExemplar methods into separate interfaces
This is, sadly, the only way to avoid a breaking change. The cost is
that anyone using exemplars has to perform a type assertion. This is,
however, a common pattern where interfaces turn out to need additional
methods in a stable library or only some implementations can provide
the additional methods (AKA "interface upgrade").

Needless to say that in v2 of this library, we'll do things in a more
straight forward way.

Damien Lespiau ec06aca188 Create Docker images for the examples
When those are published on Dockerhub, people will be able to start those
examples in fewer steps than the current documentation:

  https://prometheus.io/docs/introduction/getting_started/#starting-up-some-sample-targets

While relying on Docker may not be always wished, giving the possibility to
quickly start a daemon that exposes metrics can be useful in many tutorials.

The simple and random example are build as static binaries and packaged as
single binaries in Docker images.

This commit tries really hard to limit the number of per-example maintenance
work by sharing most of the Makefile to build the Docker images. The tiny top
level Makefiles in each example directory are strictly identical.

beorn7 9c4b7780d7 Allow Summaries with empty objectives and deprecate DefObjectives

Bjoern Rabenstein 5d40912fd2 Complete rewrite of the exposition library.
This rewrite had may backs and forths. In my git repository, it
consists of 35 commits which I cannot group or merge into reasonable
review buckets. Gerrit breaks fundamental git semantics, so I have to
squash the 35 commits into one for the review.

I'll push this not with refs/for/master, but with refs/for/next so
that we can transition after submission in a controlled fashion.

For the review, I recommend to start with looking at godoc and in
particular the many examples. After that, continue with a line-by-line
detailed review. (The big picture is hopefully as expected after
wrapping up the discussion earlier.)

Matt T. Proud 0f93b588cd Update client to reflect new API needs.
1. The output format is now versioned per the Semantic Versioning scheme.  Mainline Prometheus will be adapted to use differing consumption methodologies as the generators' formats evolve to support legacy clients.

2. The telemetry outputter now supports GZIP output encoding.  In sample runs, this cuts the output size in half.

3. Basic sanity tests are added for registration with varying levels of pedanticness.

4. We have support for base labels in the registration and emission phases.

5. We have label support for individual metric mutation operations.

6. A number of simplications have been made.
