Summary:
With `from __future__ import annotations`, all type hints become strings. The current type validator assumes that what is being checked is a type and not a string, so no types are being validated in these cases.
The fix is to use Python's typing.get_type_hints to evaluate the type hints at runtime

Pull Request resolved: facebook#333
Test Plan:
Imported from GitHub, without a `Test Plan:` line.
New unit tests were added to check that function parameters and return types were being interpreted correctly when annotated as a string (which is the case with from __future__ import annotations)
