Public bug reported:

Is there any configuration method about neutron_lbaasv2?. this problem
troubled me a long time, the doc is not very well. my lbaas'es config
file has been changed many times, but it didn't work.

my openstack version is pike.

It was relate to https://bugs.launchpad.net/barbican/+bug/1689846, but
my environment is lbaasv2, not octavia.

I tried create tls listener throuth through lbaasv2, there will be a
right response on CLI. And neutron-server.log was all right, but there
will be an ERROR in lbaas-agent.log, the log is bellow.
