Journald dependencies not installed correctly for Glance OSA role

[Joshua Lyle]

Journald is not able to be enabled for glance-api or able to be enabled with use_journal = True in /etc/glance/glance-api.conf. This is because there are no python journald bindings installed in the /openstack/venvs/glance-18.1.7.dev7 virtual environment.

The fix required running pip install systemd-python inside of the /openstack/venvs/glance-18.1.7.dev7 virtual environment to enable the systemd bindings and allow glance-api to correctly write to journald

Running head of stable/rocky at commit cf776e29a383fb7779858068369d3dfc4794141c

Running 1 infra node, 6 compute nodes, all on Ubuntu 18.04

The error that shows comes from uwsgi not being able to start glance-api after trying to enable systemd-journald journaling
