FR: Please add a filter for adding user role.

Hi all!
Have a small request/thought. When a subscription is created for a user, the give_subscriber user role is added to the user as well. However, this isn’t necessarily needed (or even wanted) in every setup. Can you please add a filter to allow devs to override whether the user role is going to be added to the user? All this would take would be to alter line 110 in wp-content/plugins/give-recurring/includes/give-recurring-subscriber.php from:

if ( ! empty( $this->user_id ) ) {
	$this->set_as_subscriber();
}

To:

if ( ! empty( $this->user_id ) && apply_filters( 'give_set_user_as_subscriber', true, $this->user_id ) ) {
	$this->set_as_subscriber();
}

A simple fix that would give devs the ability to set the parameter to false, thus bailing on the action.

Let me know your thoughts!
