networkx 2.8.3 will raise errors if certain characters, such as a colon, in the node names and the string is not quoted.
This patch double quotes flow, node, and task string representations to make sure there are not issues with these characters occuring in the names.

This library no longer supports Python 2, thus usage of six can be
removed. This also removes workaround about pickle library used in
Python 2 only.

As part of the migration of this project to the independent release
model, we failed to notice that the job template was still tied to a
specific release. We've now introduced a new unversioned job template,
'openstack-python3-jobs' [1], which was can and should use. Do this.

When catching that a redis buffer is not formatted correctly,
_fetch_jobs now deletes the data from the hashmap, so the same error
will not occur during the next call to the function.

The commit also adds JobFailure in the list of caught exceptions (might
be raised by _loads) in _fetch_jobs
