docs: This method will connect to kanbanery via basic user/pass authentication
  <strong>and will keep using it until forced to switch modes!</strong>. This method is not encouraged,
  you should use {@link JanbaneryFactory#connectUsing(String, String)} and allow Janbanery to switch to apiKey mode
  as soon as it load's up to increase security over the wire.
  
  @param user     your kanbanery username (email)
  @param password your kanbanery password for this user
  @return an Janbanery instance setup using the API Key auth, which will be fetched during construction
