* different idea for TempFile

* oh, no cleanup function

* small fixes for tests detected by 3.14

* update pytest.ini

* ignore sqlite errors during closing in __del__

* add code to ignore deprecatewarnings for loop policy

* Pass in ClientSession to wschiaconnection for proper cleanup

* Some more resource cleanup

* Trying to find unclosed sessions

* One more time needing a close

* wait for harvesters to connect to the farmer

* properly teardown vdf_server using context manager

* Testing cleanup for simulator tests

* Add in a sleep to allow sockets time to cleanup

* Revert "Testing cleanup for simulator tests"

This reverts commit c5a4ef0cc3.

* Revert "properly teardown vdf_server using context manager"

This reverts commit 18b456a7b6.

* Revert "Revert "Testing cleanup for simulator tests""

This reverts commit 8c8efc2e03.

* vdf_server cleanup

* attempt 47 of timelord cleanup

* Some other cleanup fixes in tests

* Some more adjustments for 3.14

* ignore unclosed socket resource warnings

* some more adjustments and cleanup

* remove commented code

* correct poetry.lock file

* Address some review comments

* fix merge indentation

* fix install script print

* update requests

* fix problems with timelord tests on 3.14

* Make sure to close dummy session on any exception
