Patch 1 addresses the VLAN tenant network issue.

An OVN deployment can have multiple logical switches each with a
localnet port connected to a distributed logical router with one
logical router port providing external connectivity (provider network)
and others used as tenant networks with VLAN tagging.

As reported in [1], external traffic from these VLAN tenant networks
are tunnelled to the gateway chassis (chassis hosting a distributed
gateway port which applies NAT rules). As part of the discussion in
[1], there were few possible solutions proposed by Russell [2]. This
patch implements the first option in [2].

Patch 2 adds a new logical port type - 'external' to support using
of OVN native services like DHCP for VMs which are not bound to any
ovn-controller chassis. The main use case is for SR-IOV VMs.
Patch 2 also addresses the comments from Ben about adding documenation
in ovn-architecture.

I had submitted these patches separately earlier. Now I have made it
as a series and reset the patch version to 1.

  ovn: Avoid tunneling for VLAN packets redirected to a gateway chassis
  ovn: Support a new Logical_Switch_Port.type - 'external'
