Add missing AMQP options to neutron.conf

Using the new attributes added in common, we can allow
deployers to optionally turn on durable queues, auto-delete
for queues, and enabled QPID federation support.

Bump common dependency version, since we need the attributes
introduced in 9.4

Fix symlink when main changed from ML2 to ovs

When the main plugin is changed from ML2 to OpenVSwitch, the redhat
required plugins.ini symlink does not get properly updated. Change the
symlink to rely solely on the main plugin attribute and not the conf
files as there is not a 1-1 relationship between them.  See bug for more
details.
