Some comments are copy-pasted from other, unrelated code. Documenting
a PHPUnit test file as being a "module test" is, I would argue, somewhat
pointless.

According to https://tools.wmflabs.org/coverme/?repo=Extension%3APopups
these might be relevant to cover, and already are, but the required
@covers tags have been forgotten.
Note that the MWEventLogger class does not have a dedicated test. This
is fine because it is exclusively used by the factory (as it should),
can be considered part of it, and in this case it's fine if one test
covers both.
However, none of the log() methods is covered by any test. This is for
a later patch.

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.
