"""Test downloading Ray wheels for currently running commit

This test runs on a single node and verifies that wheel URLs on all platforms
for the currently running Ray commit are valid.  This test is necessary to
catch changes in the format or location of uploaded wheels. A test like this is
is not straightforward to add in pre-merge CI because at pre-merge time, there
is no commit to master yet and no uploaded wheels.

Runtime environments use these URLs to download the currently running Ray wheel
into isolated conda environments on each worker.

Test owner: architkulkarni

Acceptance criteria: Should run through and print "PASSED"
