When the `experimental:exit-node-steering` attribute is enabled for a
node, it is likely that the priority score for an exit node is
different when considering it as a suggested exit node versus
considering it for the routers / connectors that it hosts.
In order to distinguish between these two, the network map can now
contain the priority score for suggesting the exit node in the
`suggest-exit-node` capability, in that peer’s CapMap:
"CapMap": {
"suggest-exit-node": [
{
"Priority": 42
}
]
}
