Kokoro tests not running on pull requests

[sfkhalid]

The nine kokoro tests that run on VtR pull requests are failing after a few minutes. These tests include ODIN-II strong, all four of the VtR Nightly tests, the VtR strong sanitized tests, the VtR Yosys test, the VtR Yosys+Odin-II tests, and the Yosys+ODIN-II strong tests.

Expected Behaviour

The tests should run and check whether the code on the pull request passes the required tests and produces acceptable QoR results.

Current Behaviour

The tests fail after a few minutes. This seems to be an issue with the python scripts according to the log files of the failing tests:

Steps to Reproduce

The test failures can be seen on pull requests where the tests have run recently. See: PR #1962, PR #1938, PR #1952. The failing tests ran to completion and passed on PR #1938 on Jan 24th.
This issue seems to have appeared in the last few days - sometime after Jan 27th. PR #1958 seems to be the last time they ran properly.

Context

The tests are required for pull requests to be merged, so if they cannot run, it will hold up the merging of pull requests.

@mithro Is there anyway to get this issue resolved quickly? It is blocking a few PRs. Thank you in advance.

With #1986 - Kokoro has been replaced by GitHub Action Runners and thus this bug is not longer relavent.
