Add owner references to mutator function

Fixes edge case.
The user is using limitador as a standalone product before using kuadrant and has the limitador CR called `limitador`. Once kuadrant is installed to the same namespace the kuadrant operator should take ownership of the limitador CR.

The update in this commit is only required for this use case.
