[TASK] Add functional tests for dynamic values in Extbase query cache

For performance reasons Extbase caches database queries. To ensure the
security relevant aspect, the frontend usergroup has to be parameterized
and be added by runtime. This patch adds functional tests to ensure
query caching by:

* adding possibility to simulate a frontend user in functional tests
* extending blog_example extension TCA adding fe_group for blogs
* adding a plugin and controller for blog listing
* adding new fixtures with frontend usergroups restrictions
* adding functional tests and frontend rending function
