Node 10.6.0 config and nix updates

[johnalotoski]

Description

This PR includes various SRE related changes for 10.6.0 pre-release readiness:

• Bumps iohk-nix for config updates with Node 10.6.0-pre updates input-output-hk/iohk-nix#602
• Fixes configuration change related CI checks.
• Eliminates the separation of bp and non-bp configurations into a single config whereby ouroboros-network now automatically determines PeerSharing and Target* parameters which previously required being explicitly declared.
• The new tracing system is now set as the default configuration; the legacy tracing system config is still made available.
• The mainnet default topology configuration now includes a peerSnapshot declaration for making testing of GenesisMode more convenient.
• Adjusts OCI containers for the new config setups and also includes peer-sharing configs for each network
• Updates the nixos cardano-node service for the deprecation of useNewTopology given P2P is now the only networking mode as of 10.6.0.
• Updates the nixos cardano-node service for new tracerSocketNetworkAccept and tracerSocketNetworkConnect cardano-tracer connection options.
• Updates the nixos cardano-node service to support SRV peer records.
• Updates the nixos cardano-tracer service for option name changes of acceptingSocket to acceptAt and connectingToSocket to connectTo; related workbench services were also updated accordingly.
• For the binary releases, the cardano-submit-api config and peer-sharing config was added.
• The default cardano-submit-api config was made compatible with the new tracing system.
