    [ovn]Only synchronize non dynamic segments
    
    When creating a network, only the localnet logical_switch_port
    will be created for segments with dynamic=False [1][2]. when we
    synchronize data, we should also add filtering criteria.

Title:
  OVN synchronized too many segments

Status in neutron:
  Fix Released

Bug description:
  During synchronization, OVN will query all the segments associated with the network in the current database[1]. This will synchronize the dynamic segment and create a provnet ovn logical_switch_port simultaneously.
  When creating a network, only a provnet ovn logical_switch_port  will be created for segments with dynamic=False[2][3].
