ReleasedObjectInfo
Provides the version state of a successfully released blob or container
object.
The ETag contains a value that you can use to perform operations
conditionally. If the request version is 2011-08-18 or newer, the
ETag value will be in quotes.
Returns the date and time the object was last modified. Any
operation that modifies the blob or container, including an update
of the object's metadata or properties, changes the last-modified
time of the object.
Creates a new ReleasedObjectInfo.
