This resolves the following deprecation warning:
b'/home/zuul/src/git.openstack.org/openstack/nova/.tox/functional-py35/
lib/python3.5/site-packages/oslo_service/threadgroup.py:193:
DeprecationWarning: Calling add_timer() with arguments to the callback
function is deprecated. Use add_timer_args() instead.'
The add_timer_args method was added in 1.34.0:
Ib2791342263e2b88c045bcc92adc8160f57a0ed6
So the required version of oslo.service is also updated.
