Turn filter action into conditions (#13005)

Previous logic was using the previous step output and filtering items
that were passing filters.
What we actually want is:
- send filters, right operand being always a step output key, left
operand being either a key, either a value
- resolve those filter variables
- apply the filters to decide whether the condition is passed or not
