Document mixed scenario with LB and OVS over VXLAN

Browse Source 
This patch adds a recommendation to the deployment examples in the docs
on how to configure the udp_dstport option of the Linux bridge agent to
support mixed environments, where nodes with the Linuxbridge agent must
communicate over VXLAN tunnels with nodes with the OVS agent

.. warning::
By default, Linux uses UDP port ``8472`` for VXLAN tunnel traffic. This
default value doesn't follow the IANA standard, which assigned UDP port
``4789`` for VXLAN communication. As a consequence, if this node is part
of a mixed deployment, where nodes with both OVS and Linux bridge must
communicate over VXLAN tunnels, it is recommended that a line containing
``udp_dstport = 4789`` be added to the [vxlan] section of all the Linux
bridge agents. OVS follows the IANA standard.
Replace ``PROVIDER_INTERFACE`` with the name of the underlying interface
that handles provider networks. For example, ``eth1``.
