Clay Gerrard 2759d5d51c New Object Versioning mode 
This patch adds a new object versioning mode. This new mode provides
a new set of APIs for users to interact with older versions of an
object. It also changes the naming scheme of older versions and adds
a version-id to each object.

This new mode is not backwards compatible or interchangeable with the
other two modes (i.e., stack and history), especially due to the changes
in the namimg scheme of older versions. This new mode will also serve
as a foundation for adding S3 versioning compatibility in the s3api
middleware.

Note that this does not (yet) support using a versioned container as
a source in container-sync. Container sync should be enhanced to sync
previous versions of objects.
