[Bug 1527005] [NEW] Open vSwitch and Linux bridge agent dependencies

[Matt Kassawara]

Public bug reported:

In Liberty, the Open vSwitch and Linux bridge agents use the following
separate configuration files:

/etc/neutron/plugins/ml2/openvswitch_agent.ini
/etc/neutron/plugins/ml2/linuxbridge_agent.ini

The neutron-plugin-openvswitch-agent and neutron-plugin-linuxbridge-
agent packages depend on the neutron-plugin-ml2 package that contains
these files. However, only the neutron-server component (typically on
the controller node) actually uses the ML2 plug-in and loads ML2
configuration from the ml2_conf.ini file. Other neutron components
should not use the ml2_conf.ini file, yet the init scripts for the Open
vSwitch and Linux bridge agents load it in addition to their separate
configuration files. The neutron-plugin-openvswitch-agent and neutron-
plugin-linuxbridge-agent packages should probably include their separate
configuration files instead of the neutron-plugin-ml2 package.

Also, on a somewhat similar note, the neutron-plugin-ml2 package seems
to only contain configuration files for the ML2 plug-in. The python-
neutron package (a dependency of the neutron-common package) includes
the actual code for it which means all installations of neutron include
the ML2 plug-in even if they don't use it.
