Convert bgpid, remote_bgpid and clusterid to host byte order.

Convert bgpid, remote_bgpid and clusterid to host byte order.

Before the RDE used host byte order for remote_bgpid but all the other
code used network byte order. The reason for that was that bgpid was
initially an IPv4 address but since RFC 6286 in 2011 this is much more
relaxed and so it makes more sense to just treat them as numbers and
so host byte order.
