This is needed so that when they are bundled into archives, receiving
nodes can still verify the messages payload using its signature.

This commit introduces a new `TorrentConfig` as per #2563 with dedicated
default values and new options/flags for the status-go CLI.
Since it's part of `NodeConfig`, which is stored per user in the

`torrent_config` table and database APIs to insert and retreive the
torrent config.
Closes#2563
