Enable Flake8 Docstring Errors

Flake8 currently ignores the following errors:
H401: docstring should not start with a space
H404: multi line docstring should start without a leading new line
H405: multi line docstring summary not separated with an empty line
Enable them for more consistent formatting of docstrings
