Add new filters for case sensitive match `_contains_strict` , `_starts_with_strict`, `_ends_with_strict`

As a user I think this is how you would expect this functionality to work. @lutter what do you think about making this the default for contains and starts_with, and introduce new _contains_strict and _starts_with_strict for exact matching? That would of course introduce some query variability between versions
