Since 1.16 is out, we still support the last four minor releases.
The bump was required by the prometheus/procfs package using the new
`%w` printf directives. However, it also allows us to remove some
special casing about build info.

This allows us to simplify a bunch of code while still supporting the
last four Go minor versions.
We have also run into minor annoyances a couple of times by now to
keep supporting 1.7 and 1.8.
It's time to pull the plug!

This ends a long time of not really tagging versions (as it didn't
make a lot of sense - we could have tagged every commit with a new
minor release essentially). I still worked through the git log and GH
issues to create a nice CHANGELOG.md.
As dependency management tools really love version tags these days, I
plan to tag more often from now on. The ideas behind the pre-1.0
version numbers are explained in the README.md as changed in this
commit.
I also changed the issue template accordingly.

The prometheus link in the README is broken - there is no page at www.prometheus.io (it's at promethius.io - I guess they didn't set up a redirect). @beorn7
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.)

Examining the existing documentation over the standard Go documentation
server revealed some serious formatting flaws. Everything should be
readable now.
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.
- Provide better examples in the examples subdirectory.
- Make the comments consistent in terms of using multi-line format for future-proofing.
- Extract major constants out.
