Arista: BGP neighbor next-hop-unchanged doesn't work in gated mode

A bit background, in Arista EOS, there is 2 implementations of BGP process. Default is gated, and late one is multi-agent, which can be enabled via cli - service routing protocols model multi-agent. 

BGP neighbor next-hop-unchanged is only supported in multi-agent mode, not in gated. This feature works in route-map with both modes.
