Codecoverage in codeception uses the C3 helper script that needs to be
included in the site running. This collects code coverage even
(especially) for acceptance tests, e.g. where codeception itself does
not have control over the code.
For coverage collection in general, XDebug is needed and therefore also
activated.

Production usage not yet possible due to
https://github.com/Codeception/Codeception/issues/3337 also coverage
collection is pretty slow.
