Process-compose dbsync and node stacks

[johnalotoski]

Overview:

Adds some useful process compose stacks for running cardano-node or a full dbsync stack for testnets and mainnet

Example process compose node stack running:

Example process compose dbsync stack running for sanchonet:

Details:

• Bump node to 8.7.3 from capkgs
• Bump process-compose to v0.80.0
• Add process-compose-flake and services-flake for support of process-compose run jobs
• To run, nix >= 2.17.0 is required as well as experimental-features = nix-command flakes fetch-closure in addition to flakes support
• Add process-compose stacks of:
  • Dbsync stack for each testnet plus mainnet as nix run .#run-process-compose-dbsync-$NETWORK
  • Node stack for testnets plus mainnet as nix run .#run-process-compose-node-stack

Caveats:

• State directories prefixes default to $CWD/.run and in the case of postgresql sockets $TMPDIR/process-compose
• Multiple dbsync process-compose stacks can be run concurrently without interfering with each other
• To avoid doubling node storage, node jobs and dbsync jobs for a given network use the same node state path
• In this case, only 1 of a node job from the node stack or a dbsync stack for the same network can be run at a time
