Use the `mesh_n` value from `NetworkLoad` for `PeerScoreSettings`

[jimmygchen]

Issue Addressed

We're using the libp2p default gs_config here for PeerScoreSettings: https://github.com/sigp/lighthouse/blob/6c0c41c7acecbc4d149a3715eccae24d3d3de933/beacon_node/lighthouse_network/src/service/mod.rs#L180

and then we build a Lighthouse specific one here and use it for Gossipsub https://github.com/sigp/lighthouse/blob/6c0c41c7acecbc4d149a3715eccae24d3d3de933/beacon_node/lighthouse_network/src/service/mod.rs#L266-L273

The only value that is used for initialising PeerScoreSettings from the gs_config appears to be the mesh degree mesh_n, which is taken from NetworkLoad.

Proposed Changes

Build the correct gs_config and use the mesh_n value for PeerScoreSetttings. Note that the score settings needs a bit of rework, so this would just be a temporary fix.

The impact of this fix is that scoring will now use the mesh_n from NetworkLoad (default to 4) rather than the libp2p2 hard coded value (6).

Marking this as work-in-progress as this PR is mainly for tracking and need some review from @AgeManning
