This is an Ubuntu packaging bug.  Most of the quantum pieces are still
installed and at least the metadata-agent is actually still running
and bound to the port I want.

# dpkg --get-selections | grep quantum
python-quantum                    install
python-quantumclient                install
quantum-common                    install
quantum-dhcp-agent                install
quantum-l3-agent                install
quantum-lbaas-agent                deinstall
quantum-metadata-agent                install
quantum-plugin-openvswitch            install
quantum-plugin-openvswitch-agent        install
quantum-server                    install

purging these and manually killing all the stragglers (ps aux|grep
quantum|awk '{print $2}'|xargs kill) the restarting the neutron
equivalents  once the ports are released makes everything happy.

Details to how finally noticed are inline below

Thanks,

state_path is undefined in metadata_agent.ini but is defined in neutron.conf:

/etc/neutron/neutron.conf:state_path = /var/lib/neutron

yes it is (as it should be):

# lsof | grep metadata_proxy
neutron-m 25862     neutron    4u     unix 0xffff8800b9971d40
0t0 3191905146 /var/lib/neutron/metadata_proxy

# ps 25862
  PID TTY      STAT   TIME COMMAND
25862 ?        Ss     0:00 /usr/bin/python
/usr/bin/neutron-metadata-agent
--config-file=/etc/neutron/neutron.conf
--config-file=/etc/neutron/metadata_agent.ini
--log-file=/var/log/neutron/metadata-agent.log

....BUT that's not what's listening:
