features:
- For the ``os_nova`` role, the systemd unit ``TimeoutSec`` value which
controls the time between sending a SIGTERM signal and a SIGKILL signal
when stopping or restarting the service has been reduced from 300 seconds
to 120 seconds. This provides 2 minutes for long-lived sessions to drain
while preventing new ones from starting before a restart or a stop. The
``RestartSec`` value which controls the time between the service stop and
start when restarting has been reduced from 150 seconds to 2 seconds to
make the restart happen faster. These values can be adjusted by using the
``nova_*_init_config_overrides`` variables which use the
``config_template`` task to change template defaults.
