As suggested in I69ad209.
As far as I can tell the idea was to be able to pass logger-specific
configuration to the logger factory, e.g. to be able to toggle certain
things the loggers would do. But this is not used at the moment. There
is not much value in keeping unused code around. It can esaily be
introduced again later when it turns out it is needed.
Furthermore, I'm told most of the logging functionality should be
removed anyway. See T193051.

Our documentation generator Doxygen is not able to understand @var tags
on constants. A constant is neither a "variable", nor is it possibly to
specify an allowed type for a constant. The type of a constant is strictly
derived from it's value. There is no way to change it, other than changing
the constant itself. There is not much value in repeating the type either.
If it's critical to know the type of a constant (which is a very rare
situation), that should be better explained in the comment.
Doxygen strips all @… tags it does not understand, and renders everything
else as a plain string. This makes it possible to use something like:
/**
* @const Description…
*/
But this is not different from:
/**
* Description…
*/

The code literally explains itself. The comments don't add anything
to this. They are more distracting because one must read them first
to understand they don't contain anything.

I figured a single "@covers ::__construct" in PopupsContextTest should
be enough, especially since this constructor is super trivial.
There is nothing to test in NullLogger. I also removed the duplicated
documentation as it does not really apply, and is still available in the
base class.

Introduce PopupsAnonsExperimentalGroupSize config variable. This defines
a population size who will be subject to experimentation. If the group
size is undefined or 0 (default) and PopupsBetaFeature is false
(default value) Popups will be enabled for everyone. If it is any other
value, half that group will see page previews.
Drop the config variable PopupsSchemaSamplingRate - we will now only
EventLog when an experiment is occuring. This means we can simplify the
MWEventLogger class as shouldLog will always be truthy. Given server
side eventlogging is only used for preference changes
traffic should be low and not need sampling.
Introduce getUserBucket which determines whether a user is in a bucket
on, off or control based on the value of
PopupsAnonsExperimentalGroupSize. Add tests showing how these
buckets are calculated.
Caution:
A kill switch wgPopupsEventLogging is provided for safety.
It defaults to false. Before merging, please check if any config changes
are necessary.
