So that also users of those can benefit. Obviously, we will end
updating deprecated functions one day (at latest once v0.10 is out).

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.

This is an attempt to expose
https://github.com/istio/istio/issues/8906 . The failure to do so
makes me believe the error is either already fixed in current
client_golang, or something weird I haven't spotted yet is happening
in the istio code.

it appears there is a copy/paste error in the exponential buckets test failure message which is fixed here.

This is in line with
https://prometheus.io/docs/instrumenting/writing_clientlibs/#metric-description-and-help
Since the zero value of a string in Go is `""`, we cannot distinguish
between a Help string not set and an empty Help string. Thus, we just
make it formally optional here with an encouragement to set it in the
doc comment.
In v0.10, the Help string will probably become a "normal" argument of
the constructor rather than a field in an Opts struct.

It now uses the new WrapWith function instead of ConstLabels. Describe
is now implemented via DescribeByCollect.

This unifies both constructors in one with an options argument.
The options argument allows to switch on error reporting, as discussed
in #219.
The change of the contructor signature is breaking, but only mildly
so. Plus, the process collector is rarely used explicitly. I used
Sourcegraph to search for public usages, with the following results:
- 2 occurrences of NewProcessCollectorPIDFn, once in @discordianfish's
glimpse, once in @fabxc's etcd_exporter (deprecated anyway). Both
are Prom veterans and will simply do the one line change if needed.
- 8 occurrences of NewProcessCollector, of which 7 are of the form
NewProcessCollector(os.Getpid(), "")
Thus, it's a very easy change, which I even hinted at in the doc
comment.

The only known external usage of it was in prometheus/pushgateway,
where it was removed by
https://github.com/prometheus/pushgateway/pull/200 .
Originally, the expectation was that users would implement the Metric
interface now and then. As we know now, neither it is happening, nor
would it make a lot of sense. (Users implement the Collector interface
instead.) By now, LabelPairSorter is essentially noise in the already
quite cluttered namespace in the prometheus package.
