Description of problem:
The Piwik analytics service (https://analytics.engineering.redhat.com/piwik/)
is expected to be sunset as part of the 20x20 program. The related code
should therefore be removed.
Guess we could release this with Beaker 26.0.
Piwik analytics service removed. This will be part of Beaker 26.3
Beaker 26.3 has been released.
