Import __future__ annotations (#2458)

* Import __future__ annotations

This commit...

1. adds `from __future__ import annotations` to each relevant module in order
   to enable language level type annotation support.
2. as a result most quotation marks can be removed from type annotations.

* Remove quotes from return types

* Avoid conflict with PR #2456
