Missing python-novaclient package in 'Configure network node'

[Jeff Shantz]

The end of this section instructs the reader to start the neutron-l3-agent service. This service fails to start, with no log file written.

If we manually run the same command as is run by /etc/init.d/neutron-l3-agent, we see the problem:

=====
# /usr/bin/neutron-l3-agent --log-file /var/log/neutron/l3-agent.log --config-file /usr/share/neutron/neutron-dist.conf --config-file /etc/neutron/neutron.conf --config-file /etc/neutron/l3_agent.ini --config-file /etc/neutron/fwaas_driver.ini

    import novaclient.v1_1.client as nclient
ImportError: No module named novaclient.v1_1.client

After installing the python-novaclient package, the service starts fine:

=====
# service neutron-l3-agent start
# tail l3-agent.log

I should mention that I did grep the install guide XML files for python-novaclient, and have verified that no instruction was ever given to install this package on the network node.
