ChangBo Guo(gcb) c8bb1a2755 Remove copy of incubated Oslo code
The Oslo team has moved all previously incubated code from the
openstack/oslo-incubator repository into separate library repositories
and released those libraries to the Python Package Index. Many of our
big tent project teams are still using the old, unsupported, incubated
versions of the code. The Oslo team has been working to remove that
incubated code from projects, and the time has come to finish that work.

As one of community-wide goals in Ocata, please see:
https://github.com/openstack/governance/blob/master/goals/ocata/remove-incubated-oslo-code.rst

Note: This commit also fix pep8 violations.
