Review Comment:
The IOStats won't show that rename failure happened due to parent not found
failure, since in this test we are not actually retrying successfully, as that
is hard to simulate in an integration test, so we would get the exception
thrown back after retrying once. Do you think I should change this test to
verify something differently?
In cases of actual failures we don't send back the abfsClientResult, so it
is kind of hard to test this in ITs 🤔
