Log message:
Implement send side of RFC7911 ADD-PATH
This allows to send out more then one path per perfix to a neighbor that
supports add-path receive. OpenBGPD supports a few different modes to
select which paths to send:
- all: send all valid paths (the ones with a * in bgpctl output)
- best: send out only the single best path
- ecmp: send out paths that evaluate the same up and including
the nexthop metric
- as-wide-best: send out paths that evaluete the same up but not including
the nexthop metric
Currently ecmp and as-wide-best are the same. On top of this best, ecmp
and as-wide-best allow to include extra paths (e.g. best plus 2) and
for the multipath modes there is also a maximum (e.g. ecmp plus 2 max 4)
