Add a NullHandler when setting up library logging

I was gunna write a test, but mocking ImportErrors is a PITA, so I decided to
just get my tox py26 working instead.  Tests seem to fail/pass as expected
without/with the inline NullHanlder.

Reformat help outputs

Reformatted the help outputs in the swift client to bring them more
in line with the rest of the openstack clients. Changes were added to
all of the st_command_help variables and a new variable
st_command_options was added to help with correct formatting of
help outputs.

Remove redundant unit suffix

Transfer speed already has a "MB/s" unit. The "s" suffix was probably a
copy/paste mistake.

This is a precursor to having them run under check and gate.

Sync with global requirements

Specifically, removing d2to1 is the important part. While we're at it
though, use hacking to get the pyflakes/pep8 pins.
