s3: fix SetModTime on GLACIER/ARCHIVE objects and implement set/get tier
- Read the storage class for each object
- Implement SetTier/GetTier
- Check the storage class on the **object** before using SetModTime
This updates the fix in 1a2fb52 so that SetModTime works when you are
using objects which have been migrated to GLACIER but you aren't using
GLACIER as a storage class.
Fixes #3522
