When ``auto_upload_slots_rate_based`` is set, and ``auto_upload_slots`` is set,
the max upload slots setting is ignored and decided completely automatically.
the max upload slots setting is used as a minimum number of unchoked slots.
This algorithm is designed to prevent the peer from spreading its upload

``use_parole_mode`` specifies if parole mode should be used. Parole mode means
that peers that participate in pieces that fail the hash check are put in a mode
