[PATCH v2 2/3] perf test: Add skip list for metrics known would fail

From: Weilin Wang
Date: Fri Jun 09 2023 - 12:26:55 EST


Add skip list for metrics known would fail because some of the metrics are
very likely to fail due to multiplexing or other errors. So add all of the
flaky tests into the skip list.
