Add the ability to agree to prompts via flags

[sethforprivacy]

While I understand the intent of the agreement prompts that are required on first-run, it adds a lot of complexity for use-cases where the binary is run in Docker or similar setups.

Would it be possible to add a flag that bypasses this consent? At present there is no real way to run phoenixd in a detached state until you first agree to the prompts.

Let's add the flag --agree-to-terms-of-service via change similar to this:

Another alternative approach is described in https://github.com/ACINQ/phoenixd/issues/3 - make it possible to provide the seed via env variable PHOENIXD_SEED (and in this case the daemon does not show the interactive UI.
