---------------------------------------------------
{{If the ETag does not contain the number of MPU part (e.g. legacy MPU key),
don't return the response header.}}
What is the format of this ETag? How is it different from the ETag with MPU in
it?

> Possible implementation: Since ETag of MPU key suffix is the number of the
> parts in the MPU, we can use that instead. If the ETag does not contain the
> number of MPU part (e.g. legacy MPU key), don't return the response header.
> Should be tested using unit tests and acceptance tests.
