Fix Teardown and Collection of Results of Longevity Tests

[mpstefan]

Currently, during the teardown and collection of our longevity tests, sometimes, no results are recorded for the run. We need an investigation into why this is occurring and a fix before 2.1s release.

Acceptance

• Consistent recording of longevity test results.
• General formatting of results and naming of files should be corrected

Possible Causes

• Kubernetes connection errors
• Failure to collect traffic summary
• Failure to collect logs
