Store in bgp_node the reason why we choose a particular
best path over another. At this point we do not do
anything other than just store this data when we make
the decision. Future commits will display it.

Instead of just passing in the prefix, pass in the particular
bgp_node we are using.
This is setup for a future commit to use this data.
The long term goal is to collect data about why
a particular bgp_path_info was selected as best and
to display that reason.

If no_fwd bit not set,
forward on all interfaces including which it came.
store it in bsm list with size for forwarding it later to new neighbor.
calculate PIM mtu of the interface, if bsm size is more do sematic frag and send
