7620: Start removing dependencies on requests (#7643)

* 7620: Start removing dependencies on requests

* Patch urllib.request.urlopen instead of requests.get

* Try to fix flake8

* More work on flake8 import errors

* First attempt at using urllib with cookies

* Fix pylint/flake8

* Fix test_deliver_slice_csv_attachment

* Fix test_deliver_slice_csv_inline

* Import requests and pydruid conditionally, remove dependency on prison

* Fix flake errors

* Fix load_examples

* Please flake

* Skip tests depending on optional deps

* Try to please flake

* Address review comments

* Remove Druid-related UI

* Revert "Remove Druid-related UI"

This reverts commit d7e0f166cc3f3dd2496b4a666e177f0c191aeb0f.

* Skip a few tests more

* Put imports in right order

* Apply black patch

* Please flake

* Please black, silence flake

* Use flake8 silencing the right way

* Add deps for CI
