The test_while_is_not function relied on strings and literals to test
the 'while_is_not' function. But the while_is_not function uses the 'is'
operator to test the equivalency of 2 objects.
This triggers a bug with python 3.11 where using 'is' with literals is
not advised (it is not recommended since python 3.8 [0]).
The test now uses objects from a specific class to evaluate the
while_is_not function.

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.

The mock third party library was needed for mock support in py2
runtimes. Since we now only support py36 and later, we can use the
standard lib unittest.mock module instead.

Redis client has an ability to connect to Redis server
using Sentinel[1] (especially important for Redis clusters),
but this ability was missing here.

Allow to pass 'sentinel' variable to Redis conf, extend
_make_client to use sentinel for that case.

With the removal of Python 2.x we can remove the unittest2 compat
wrappers and switch to assertCountEqual instead of assertItemsEqual

We have been able to use them since then, because
testtools required unittest2, which still included it. With testtools
removing Python 2.7 support [3][4], we will lose support for
assertItemsEqual, so we should switch to use assertCountEqual.

The networkx 2.x series has been out for two years now and supports
python 3.6 and greater[1]. This patch updates TaskFlow to require
a minimum of networkx 2.1. It also updates the code to support
recent deprecation expiration introduced in the 2.4 release.
