Title:
  network_vlan_ranges in ovs_quantum_plugin.ini is never used

Status in OpenStack Quantum (virtual network service):
  Invalid

Bug description:
  In quantum/plugins/openvswitch/agent/ovs_quantum_agent.py,
  (stable/grizzly) lines 143 and 146 set lower and upper bounds for VLAN
  ranges. Lines 167-169 then set those bounds as the
  available_local_vlans:

  
  167         self.available_local_vlans = set(
  168             xrange(OVSQuantumAgent.MIN_VLAN_TAG,
  169                    OVSQuantumAgent.MAX_VLAN_TAG))

  Then, if we jump forward to def provision_local_vlan (lines 291-310),
  specifically 304:

  304         lvid = self.available_local_vlans.pop()

  we see that lvid is set to the first value on the stack, but this
  value has never been read in from ovs_quantum_plugin.ini nor the
  quantum DB, so it will always default to whatever the lower bound
  (MIN_VLAN_TAG) is hardcoded to.

  quantum-server looks to parse this properly, as it inserts the correct
  tuples into the DB.
