Multiple operands for filter operators (#4964)

* Firt pass at adding multiple operands to filter operators

* Optimized parsing of multiple operands and added more tests. Need more flexibility for interpreting multiple operands as variables/text references

* Add support for parsing text references and variables in multiple operands

* Added string-replace filter for testing multiple filter operands

* Added more tests for variables and text references in operands

* Removed string-replace operator and some whitespace corrections

* Removed string-replace operator and some whitespace corrections

* Added test with comma in operand
