Fixing introspect bug
Fixing introspect bug

When accessing control-node introspect,
bgp standard communities does not show up
that are configured as part of static routes.
It is seen that extended communities associated
with static routes override the bgp standard communities
in introspect.
Modify method FillRoutePathExtCommunityInfo
in /opt/stack/contrail/controller/src/bgp/bgp_route.cc
to avoid overwriting bgp standard communities.
