    Ensure redirect-type=bridged not used for geneve networks
    
    As part of [1] the redirect-type=bridged flag was enabled by default.
    However this have the side effect of also decentralizing N/S traffic
    for geneve tenant networks, breaking the VM connectivity on them when
    it must be centralized, i.e., when no FIPs are associated to the VMs.
    
    This patch differentiates and only enable that flag when the networks
    conected through that router gateway port are of VLAN/FLAT type.
    
    In addition, to avoid MTU issues for the VLAN networks if there are
    also geneve networks connected to the same router, we re-take the
    approach on [2] to ensure the traffic is centralized but not tunneled

Title:
  [ovn] N/S traffic for VMs without FIPs not working

Status in neutron:
  Fix Released

Bug description:
  The N/S traffic for VMs without FIPs is not working due to redirect-
  type=bridge option being set on cr-lrp for routers with geneve tenant
  networks connected to it. It seems this flag should only be used for
  vlan networks, and not for geneve

  This option was recently added as part of [1]
