The NodeId should be a command line argument like port number.
With the current scheme one is forced to have one node configuration file per node in a topology file.

@karknu, I think the node Id should be inferred from the PBFT leader credentials, not specified at all.

PBFT indeed doesn't need it anymore (IntersectMBO/ouroboros-network#1192).

If we need anything like this at all, it's only to allow sharing a network configuration description between multiple nodes. It has no connection whatsoever to any notion of node id from consensus (since there is no such notion).

335: Implement real vs mock protocol selection r=Jimbo4350 a=Jimbo4350

Implements the `NodeProtocolMode` type which differentiates whether the node is running a real protocol vs a mock protocol.
Changes:
- When running a real protocol, the topology comes from a `JSON` file which is decoded to `RealNodeTopology` which specifies the addresses the node intends to connect to.
- `socket-dir` command line argument is changed to `socket-path` i.e you must specify socket paths and not dirs anymore.
- `NodeId` only needs to be specified for mock protocols (https://github.com/input-output-hk/cardano-node/blob/d24cefd7a4fb1afbf13e8e7f7971e22704673f98/cardano-config/src/Cardano/Config/Protocol.hs#L129)

The `cardano-node` client is now as follows (with further help for both `run` and `run-mock` via `cabal exec cardano-node run/run-mock -- --help`):
```
Usage: cardano-node (run | run-mock) [--help]
  Start node of the Cardano blockchain.

Available options:
  --help                   Show this help text

Execute node with a real protocol.
  run                      Execute node with a real protocol.

Execute node with a mock protocol.
  run-mock                 Execute node with a mock protocol.
```
