This reverts commit b5208d627b4525a44519537e38c17b057b8eb792.

Add a `--testnet-config-dir` flag that auto-discovers the 4 infrastructure
parameters (socket path, signing key, node config file, target nodes) from
a `cardano-testnet` output directory.  Discovered infrastructure always
overrides user-provided values; all other config fields must be supplied
by the user.
