When using the IpNetnsExecFilter, if the nested command is not found, the exception raised is NoFilterMatched when I think it should be FilterMatchNotExecutable.
The command run is in this log message:
2016-03-08 17:32:57.522 20681 DEBUG neutron.agent.linux.utils [req-1033d4e2-9705-47d4-8daf-bf9746b27a45 TestHealthMonitors-254658321 -] Running command (rootwrap daemon): ['ip', 'netns', 'exec', 'qlbaas-ba5ba518-5327-4f19-9e3a-d26d643a479f', 'haproxy', '-f', '/opt/stack/data/neutron/lbaas/v2/ba5ba518-5327-4f19-9e3a-d26d643a479f/haproxy.conf', '-p', '/opt/stack/data/neutron/lbaas/v2/ba5ba518-5327-4f19-9e3a-d26d643a479f/haproxy.pid'] execute_rootwrap_daemon /opt/stack/new/neutron/neutron/agent/linux/utils.py:100
