addons: support for new addon module for vrf

Browse Source 
This patch adds initial support for vrf in ifupdown2.

Example interfaces file section:
auto swp1.100
iface swp1.100
    vrf blue

auto blue
iface blue
    vrf-table 10

iproute2 vrf map is generated under:
/etc/iproute2/rt_tables.d/ifupdown2.vrf_map

this patch also adds prelimnary support for 'vrf-table auto'.
But this needs more work.
