Opens a blob for append. If the blob is being created or the existing blob type is Append
then it will be efficiently processed as an Append blob. If the existing blob is type Block
then the type can't be changed and an inefficient workaround is used to merge the old and
appended data into a work blob which is then copied back over the original at close time.
