Integrate latest 3.12.1 changes (#347)

* Bumping example to the latest version

* Adding option `skipFastLockRound` for transactions

* Introducing HTTP DELETE `/_admin/log/level` to reset all log

* Removing types-pkg-resources

* Setting skip_fast_lock_round to None by default

* Adding test coverage for `server_id` parameter
