This commit is a squash of 3 different commits required to fix
DragonFlow gate (See below).
Upgrade redis driver
Redis python package API was changed over time, while we did not
change our handling of the code.
In the gate the driver was updated, and the gate tests were broken.
Updated the code in a way that supports both python2 (soon to be
obsoleted) and python3.
Updated the requirements to install new versions of the packages.
Remove testing revision number in test_df_qos_driver
This code tests Neutron behaviour of increasing the revision number.
This is not code that is controlled by Dragonflow. If (when) it fails,
Dragonflow cannot fix it generically.
use payloads for ROUTER_GATEWAY events
This patch switches the code over to the payload style of callbacks [1]
for ROUTER_GATEWAY events for those that are not using them yet.
The unit tests are also updated where needed to account for the
payload style callbacks and publish() method. Finally the patch
normalizes the passing of gateway IPs which are currently referred to
as 'gw_ips' and 'gateway_ips' depending on the event; now all events use
'gateway_ips'.
