Test Plan: Toss an optional/required in an arg list,
check that it's ignored and compiler spits a warning

{code}

Nevertheless [Thrift IDL|https://thrift.apache.org/docs/idl] states that Field token can optionally contain optional/required keyword.

This behavior can be workarounded by usage of synthetically created struct with optional fields passed as a single argument instead of whole argument list. But this approach is not native.

The question is why this functionality was omitted and is that reasonable to implement it nowadays?

Thanks!
