Fixes bug 1023167. The openswitch plugin's in-memory VlanMap is replaced with a vlan_ids DB table similar to that used by the linuxbridge plugin. This will prevent conflicting VLAN assignments if multiple server replicas are run, and also sets the stage for phase 2 of the provider-networks BP implementation that will add support for multiple physical networks. Unlike with the current linuxbridge plugin, the contents of the openvswitch plugin's vlan_ids table are properly updated at startup in case the vlan_min or vlan_max configuration variables have changed. A new test_ovs_db test case has been added. The primary key of the vlan_bindings table is changed from the vlan_id to the network_id, which is now a foreign key, and network deletion is now properly handled. The net_id has been removed from the VlanIdInUse exception, requiring a minor update to the linuxbridge plugin. The new NoNetworksAvailable exception, with ResourceExhausted as its base class, is returned when no more VLANs are available. Change-Id: I65a2347dea5366cc0d15d98a88f40e42e1a45f4c
