Updated the SharedConfigMessage type to have a TTL of 30 days Updated the SnodeAPI to have a 'poll' method to be more consistent with the OpenGroupAPI (it also does multiple things now so is cleaner) Added logic to limit the number of config messages to be retrieved per poll Added the 'ValidatableResponse' protocol to standardise SnodeAPI response validation Added the libSession version to the logs Fixed an issue where the user profile pic wouldn't get synced correctly due to memory going out of scope Fixed some threading issues Refactored the thread variants to follow the updated terminology (will think about refactoring other code areas later) Cleaned up the Combine error handling Started fixing broken unit tests
