Merge JoinMarket-Org/joinmarket-clientserver#1235: Update local Tor config

2692f08d3b Update local Tor config (Kristaps Kaupe)

Pull request description:

  * Change loglevel to "warn" to have less verbose output (it still outputs some "notice" level messages for me but less than without this).
  * Add [stream isolation](https://github.com/JoinMarket-Org/joinmarket-clientserver/issues/583).
  ```
  IsolateDestPort Don’t share circuits with streams targeting a different destination port.

  IsolateDestAddr Don’t share circuits with streams targeting a different destination address.
  ```
  * Cookie authentication.
