Subject: Unify container wrapping (#8312)

* Method names unified to withXyzFilter
* withConfigurableFilter moved to DataProvider
* Remove DataProviderWrapper.convert since it does the same as
DataProvider.withConvertedFilter
* Make javadocs slightly more consistent
* Make type parameters consistent
