Remove `wallet_propose` method (Version: *)

[WietseWind]

Summary

Rippled implements the wallet_propose method. I feel it may be a good idea to remove this from rippled and move it to a separate tool.

Motivation

There are many secret/seed/... formats/methods to generate accounts going around, like:

• Family Seed (now part of wallet_propose)
• Word word word word
• BIP* Mnemonic
• Secret Numbers (XRPL community pushes migrating from family seeds to Secret Numbers)

I feel it would be better to have a small, standalone tool for account generation (proposing "wallets") than this being part of rippled.

Solution

Remove & standalone tool implementing multiple formats/methods to generate accounts

[intelliot]

Sounds reasonable; the first step here would be to create / document the standalone tool and make sure it serves all the use cases that wallet_propose did.

As long as the "standalone" tool is truly standalone (a single binary, not something JavaScript with a few GB of node_modules) sure, why not.

I would like to work on this, could you assign this to me please?
