socks5 tests are still failing - https://spruce.mongodb.com/task/mongo_node_driver_rhel80_large_hydrogen_test_socks5_patch_134d32ffe0b37977d71508a2f4484ba60139c9fc_6447b201d6d80a48233dd285_23_04_25_10_57_06/logs?execution=0&sortBy=STATUS&sortDir=ASC

We should establish why the tests are still failing before merging this change

Just note Socks5 tests are no longer failing, it's CSFLE tests using the setup method (https://parsley.mongodb.com/evergreen/mongo_node_driver_rhel80_large_hydrogen_test_socks5_patch_134d32ffe0b37977d71508a2f4484ba60139c9fc_6447b201d6d80a48233dd285_23_04_25_10_57_06/0/task?bookmarks=0,2618). Adding commit to attempt to debug the new failures.

Current failures same as main branch with missing Range options: https://spruce.mongodb.com/task/mongo_node_driver_next_rhel8_custom_dependency_tests_run_custom_csfle_tests_5.0_master_ce8e69b6db0eb4c0b9271ce43e334d70b967d227_23_05_01_17_15_46/logs?execution=0&sortBy=STATUS&sortDir=ASC

LGTM

the failures are different than the one we're fixing here which is the flaky primary scenario. There's the index test change that will fix when we publish a new version of FLE and what looks like flaky KMS request which we have a separate ticket for.

@dariakp, re: my comment above, is that satisfactory for merging?
