Code Issues Proposed changes

Update git submodules 

* Update neutron from branch 'master'
  - Merge "Set binding profile directly from OVNTrunkDriver (redo cont.)"
  - Set binding profile directly from OVNTrunkDriver (redo cont.)
    
    This is a tweak to changes done to fix bug 1834637. Specifically,
    this change addresses scaling. The previous gerrit change had
    modifications to all OVN sub-ports performed as a single
    transaction. That did not account for race-condition on neutron
    DB queries, which leads to timeouts under heavy loads.
    
    Another cleanup done by this change is to fold an additional
    update on neutron db into ovn trunk driver. That saves
    update from doing another database transaction, thus making
    it faster. The no longer needed function in mech_driver was
    called _update_subport_host_if_needed
    
    By breaking the iteration into multiple transactions, the
    change in time is marginal:
    
      Service-level agreement
      NeutronTrunks :: neutron.create_trunk
    
      from 34.2 sec to 35.6 for 50%ile
      from 35.6 sec to 36.1 for 95%ile
    
    This patch is a cherry pick from networking-ovn stable/train [1], that
    is now part of networking-ovn migration to neutron repo.
