This patch introduces VXLAN support for Linuxbridge agent alongside with ml2 plugin support in linubridge mechnism driver. A new vxlan configuration section is added for vxlan related parameters. The agent also implements l2population RPC callbacks which allows ml2 plugin using l2population mechnism driver to populate vxlan forwarding and neighbor tables following portbinding events. It allows agent to respond locally to ARP requests for remote VMs and avoid dataplane based learning. This should help limiting the use of multicast or flooding for broadcast emulation in vxlan networks. These changes should anyway have a limited risk, as agent behaviour shouldn't be affected, except when vxlan is enabled alongside ml2 plugin. Implements: blueprint l2-population Change-Id: I99a961c53f9e451409f1affb079042936d8ae5c6
