Fail run conformance test make target on test failure

[ciarams87]

Proposed changes

Problem: The conformance tests jobs are not being marked as failed in the pipeline even when there are failed tests. This is because the last command in the pod and the Make target relate to the conformance profile report and not the tests themselves, so the exit code is always 0 as long as the job completes.

Solution: Fetch the test result from the conformance profile yaml and exit with 2 if there's a failure result

Testing: Tested the conformance tests locally and verified that the make target fails when there's a failure in the conformance tests, and doesn't fail when there isn't

Closes #1176
