New netlink api to associate tunnel info per vlan.
This is used by bridge driver to send tunnel metadata to
bridge ports in LWT tunnel dst metadata mode.

One example use for this is a vxlan bridging gateway or vtep
which maps vlans to vn-segments (or vnis). User can configure
per-vlan tunnel information which the bridge driver can use
to bridge vlan into the corresponding vn-segment.

This patch also introduces a bridge port flag IFLA_BRPORT_LWT_VLAN
to enable this feature on a tunnel bridge port. It is off by default.

since it does not use the LWT infra, I plan to drop any LWT references and call
the new features and modes plain collect metadata or dst_metadata mode in the next version.
