Neutron: Define a utility function to add neutron service class
When enabling neutron service (i.e. enable_service q-xxx), related code
unconditionally adds a necessary plugin class to Q_SERVICE_PLUGIN_CLASSES.
Which may cause duplication in Q_SERVICE_PLUGIN_CLASSES when
Q_SERVICE_PLUGIN_CLASSES is explicitly specified in localrc.
As a result, neutron server fails to start.
This patch introduces a utility function to add service class,
and check duplication.
Closes-Bug: #1261291
