Description

This task is going to refactor current striped file test case structures, especially StripedFileTestUtil file which is used in many striped file test cases. All current striped file test cases only support one erasure coding policy, that's the default RS-DEFAULT-6-3-64k policy. The goal of the refactor is to make the structures more convenient to support other erasure coding policies, such as XOR policy.
