Swift in 4.2 is broken, anybody wants it to be supported in 4.2?

[Edison Su]

Due to object store refactor, Swift is broken. The reason, is that, we only 
have S3 test environment in our lab, so only S3 is tested for now.
Before adding the feature back, I'd better ask from, the community, do we want 
to support Swift? If so, which version of Swift? This will take some efforts to 
support Swift, are there any volunteers can help the integration?
