Update keystoneclient code to account for hacking 0.9.2

Fixed most of the errors reported back from hacking 0.9.2.
Specifically:
- E128 continuation line under-indented for visual indent
- E251 unexpected spaces around keyword / parameter equals
- E265 block comment should start with '# '
- H305 imports not grouped correctly
- H307 like imports should be grouped together
- H402 one line docstring needs punctuation
- H904 Wrap long lines in parentheses instead of a backslash

But opted to ignore the following for now:
- E122: continuation line missing indentation or outdented
- H405: multi line docstring summary not separated with an empty line
