Reformat docstrings that exceed 80 columns

Our style guide and flake8 require that lines in our Python code do not exceed 80 characters. Some docstrings do not follow this convention and should be reformatted to follow it when possible.

You can find a list of such strings with this command: grep '""" *# noqa' ../*/swh -r.

The following packages have offending lines. I will fix the lines wherever possible.
