Review Comment:
This performs a second network call (`setHttpHeaders`) after upload to set
`Content-MD5`. Consider setting headers as part of the initial upload request
(using an upload options overload that accepts `BlobHttpHeaders`) so the upload
+ properties update is done in one request, avoids extra latency, and prevents
ending up with an uploaded blob missing MD5 if `setHttpHeaders` fails.
