Enable configuration of Neutron QoS

This change adds support for setting the configuration options required
to enable the quality of service feature in Neutron. The default values
will enable the feature.

Note: this is a resubmission of a backport that was reverted by commit
c495eab279 to address a problem in the
neutron puppet modules. The fix to the puppet modules appears to be
merged to the appropriate stable/liberty branches so this backport
should be okay now.

Closes-Bug: #1524052

Depends-On: Iefc289a6eee13b9c66f8131c258af982f232df4b

(cherry picked from commit c9f12915ef)
