Default peerSharing true and add block producer config to release binaries

[johnalotoski]

Description

• Bump iohk-nix to:

  • Default node config to use PeerSharing true with TargetNumberOfRootPeers reduced from 100 to 60
  • Make available a block producer config which keeps PeerSharing disabled
  • Adds MinNodeVersion to node config to indicate the lowest compatible version of node with the config

• Adds config-bp.json block producer configs for each environment to the release binary artifacts

• Tree diff of the gzip expanded and untarred release binary show a new config-bp.json file for each env:

# Build the artifact before and after PR with:
#   `nix build -L .#hydraJobs.x86_64-linux.musl.cardano-node-linux`
# Compare the expanded result/cardano-node-8.10.0-linux.tar.gz
