Bug Description

This is due to oslo_service/systemd.py that sends a string rather than a "byte-like object"
python3 is more explicit on types.

# cat /etc/systemd/system/multi-user.target.wants/neutron-metadata-agent.service
[Unit]
Description=OpenStack Neutron Metadata Agent
After=syslog.target network.target

# systemctl start neutron-metadata-agent.service
Job for neutron-metadata-agent.service failed because the control process exited with error code. See "systemctl status neutron-metadata-agent.service" and "journalctl -xe" for details.
