[TieredStorage] Put commonly used test functions into test_utils.rs (#…
…35065) #### Problem There're some test functions that have been used in different mod in TieredStorage. It's better to have one same place for all tiere-storage related test functions. #### Summary of Changes Created test_utils.rs under /tiered_storage and move test-related functions into it. #### Test Plan Existing tests.
