Code Issues Proposed changes

Remove pep8 whitespace ignores 

We had carried over the full list of pep8 whitespace ignores from nova.
Trying to address them all in the entire nova repository would have been
too big a task; but it's tenable here in placement.

Do it now rather than letting these whitespace issues compound.

This change removes the E* whitespace ignores and fixes the pep8 issues
they were masking.
