Run functional and NFR tests with --race

[sjberman]

Problem: The functional and NFR tests do not run with --race enabled, so race conditions within the tests may be present and unknown.

Solution: Enable --race and fix any issues.

Testing: Verified that all tests run.

Please focus on (optional): If you any specific areas where you would like reviewers to focus their attention or provide
