Custom RPC methods and regular RPC APIs should be managed via TOML configfile.

[CPerezz]

In our docs is said:

Edit src/whitelist.rs to modify allowed methods:

const ALLOWED_METHODS: &[&str] = &[
    // Add your custom methods here
    "eth_blockNumber",
    "eth_getBalance",
    // ...
];

Notice that this won't allow operators to download pre-compiled binaries nor anything similar.

Thus, we should allow a more configurable and release-friendly approach that doesn't enforce the user to re-compile the whole code each time they want to update the API that is exposed.
