Updated openstack/openstack
Project: openstack/taskflow  887fc9b768c30cc78c5962ca7df0a3ce0a9a9bd6

Tweaks to setup.cfg

Add in 3.4 classifier (and adjust spacing of the
classifier section) since 3.4 support will be maintained
ongoing in the future.

Adjusts the keywords to be a smaller list of comma
separated values that summarize what taskflow is all
about.

Adds python2.6 as a minimum version so that it is well
understood (it was already implied) what the minimum
python version we currently support is.

Hopefully this adjustment fixes bug 1323731
