Public bug reported:

In line
https://opendev.org/openstack/neutron/src/branch/master/neutron/agent/l3/keepalived_state_change.py#L172
there is a `conf.set_override('debug', True)` which enables debug mode
for neutron-keepalived-state-change.

This means any setup by the operator in the configuration file is
ignored.

In certain scenarios the log can flood the system with messages like the
following:
