feat(wallet-daemon): add new authentication method

[ksrichard]

Context

We must have an authentication method in wallet daemon to avoid any attacks that ends with stolen funds for example.

Proposal for authentication method

Use Webauthn (more info about the flow: webauthn.me) as an optional authentication method in wallet daemon.
This method allows us to securely do authentication on a public/private key basis. You are also allowed to use security hardware devices like Yubikey.
This method works perfectly on browser, but it needs to be working from CLI or code to call RPC methods.

Proposal for CLI

Webauthn authentication can work like we generate a simple URL that the user can open in browser, do authentication to get a token that can be pasted to the CLI prompt to make it working.

Proposal for RPC calls from code

TBD
