Introduce new parameter Expected Failures List

The Expected Failures List parameter will help with specifying set
of tests whose failures we want to ignore. By adding test to this
list, its failure will not have impact on the jobs pass/fail. It
can help with not having to re-run long running jobs and save
time and resources in specific cases, for example when dealing
with flaky tests.
