support multihop ttl
You can enable the feature like the following:
[Neighbors]
[[Neighbors.NeighborList]]
[Neighbors.NeighborList.NeighborConfig]
PeerAs = 65001
NeighborAddress = "10.0.255.1"
[Neighbors.NeighborList.EbgpMultihop]
[Neighbors.NeighborList.EbgpMultihop.EbgpMultihopConfig]
Enabled = true
MultihopTtl = 8
