Summary

In BUILD-17302 we identified that drivers were removing the instance profile from the EG EC2 hosts to support the AWS web identity tests, which was interfering with other test runs using the same host.
In DRIVERS-2639 we worked around the problem by ensuring that the instance profile was reinstated during task teardown.

The better long-term solution is to use Kanopy for the web identity tests by leveraging IAM roles for service accounts.
