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
