mypy depends on typed-ast which relatively recently added python 3.8 support. Unfortunately the mypy we were using requires an older typed-ast and fails under python 3.8. Fix this by bumping mypy up to a level where minimal code changes are necessary. The code changes we made ignore type conflicts due to redefinition on conditional imports. Comments include link back to a bug describing this issue and workaround in mypy. Change-Id: Iec69a27b16a1e09eb6bfbcf8d68deb1ae68d42a3
