Expose LibTorrent peer_turnover settings

Browse Source 
This PR exposes the LibTorrent Peer Turnover Settings in qBT Advanced Settings in order to allow users to adjust how frequently slow and uninteresting connections are closed to allow potentially better / faster connections to be made.

The default settings are to turnover peers when the number of connections is at least 90% of allowed global or per torrent connections, and to disconnect the least attractive 4% of these connections every 5 minutes.

See https://www.libtorrent.org/reference-Settings.html#peer_turnover
