[Bug 1460228] [NEW] neutron-lbaas-agent package does not provide neutron_lbaas.conf file

[Colleen Murphy]

Public bug reported:

Description of the problem:

The neutron release notes for OpenStack Kilo
(https://wiki.openstack.org/wiki/ReleaseNotes/Kilo) indicate that
individual neutron plugin packages are supposed to provide their own
/etc/neutron/neutron_*.conf files, and each will specify their own
service_provider options. The neutron-vpn-agent package provides
/etc/neutron/neutron_vpnaas.conf, as expected. The neutron-lbaas-agent
package does not provide /etc/neutron/neutron_lbaas.conf or anything
similar.

Impact:

Attempting to use the lbaas plugin by specifying lbaas as one of the
DEFAULT/service_plugins values results in neutron-server being unable to
start correctly, with the following error in the log:

ERROR neutron.services.service_base [-] No providers specified for
'LOADBALANCER' service, exiting

The workaround is to add /etc/neutron/neutron_lbaas.conf with the
content

[service_providers]
service_provider=LOADBALANCER:Haproxy:neutron_lbaas.services.loadbalancer.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

An alternative workaround is to add this section to
/etc/neutron/neutron.conf, but then this also requires moving the
analogous parameter from /etc/neutron/neutron_vpnaas.conf into
/etc/neutron/neutron.conf, or neutron fails with a different error about
the VPN service.

Expected behavior:

/etc/neutron/neutron_lbaas.conf exists, contains default content:

[service_providers]
service_provider=LOADBALANCER:Haproxy:neutron_lbaas.services.loadbalancer.drivers.haproxy.plugin_driver.HaproxyOnHostPluginDriver:default

Actual behavior:

/etc/neutron/neutron_lbaas.conf does not exist, and neutron-server won't
start if lbaas is specified as a service_plugin.

Steps to reproduce:

1) Install neutron-server
2) Install neutron-lbaas-agent
3) Add 'lbaas' as one of the values for the parameter DEFAULT/service_plugins in /etc/neutron/neutron.conf
4) Restart neutron-server
