ML2 VxlanTypeDriver: Synchronize of VxlanAllocation table

At neutron startup VxlanTypeDriver syncs tunnel range from conf
to DB. In case multiple servers deployment restarting several
servers at the same time could lead to DB exceptions being thrown.
Need to synchronize between neutron servers by locking VxlanAllocation
table.
