Fix functional tests failure

[luckyj5]

Functional tests are failing randomly in CI setup when running all the tests together.
But tests are not failing when running them in groups (Splitting the tests in 2 or 3 sets and run them in parallel). Need to investigate and troubleshoot to figure out the root cause and fix the failure.

@luckyj5 - is this still issue. Update and close accordingly.

Yes, functional tests were failing randomly and hence were not included as part of the CI pipelines. This needs to be looked at and could be a part of CI migration to CircleCI process.
@gp510 Can you take a look at this when you work on CircleCI stuff?

@dtregonning @luckyj5 - Yes I am looking into this
