> Update WASB driver to use the latest version (5.2.0) of SDK for Microsoft
> Azure Storage Clients. We are currently using version 4.2.0 of the SDK.
> Azure Storage Clients changes between 4.2 and 5.2:
> * Fixed Exists() calls on Shares and Directories to now populate metadata.
> This was already being done for Files.
> * Changed blob constants to support up to 256 MB on put blob for block
> blobs. The default value for put blob threshold has also been updated to half
> of the maximum, or 128 MB currently.
> * Fixed a bug that prevented setting content MD5 to true when creating a new
> file.
> * Fixed a bug where access conditions, options, and operation context were
> not being passed when calling openWriteExisting() on a page blob or a file.
> * Fixed a bug where an exception was being thrown on a range get of a blob
> or file when the options disableContentMD5Validation is set to false and
> useTransactionalContentMD5 is set to true and there is no overall MD5.
> * Fixed a bug where retries were happening immediately if a socket exception
> was thrown.
> * In CloudFileShareProperties, setShareQuota() no longer asserts in bounds.
> This check has been moved to create() and uploadProperties() in
> CloudFileShare.
> * Prefix support for listing files and directories.
> * Added support for setting public access when creating a blob container
> * The public access setting on a blob container is now a container property
> returned from downloadProperties.
> * Add Message now modifies the PopReceipt, Id, NextVisibleTime,
> InsertionTime, and ExpirationTime properties of its CloudQueueMessage
> parameter.
> * Populate content MD5 for range gets on Blobs and Files.
> * Added support in Page Blob for incremental copy.
> * Added large BlockBlob upload support. Blocks can now support sizes up to
> 100 MB.
> * Added a new, memory-optimized upload strategy for the upload* APIs. This
> algorithm only applies for blocks greater than 4MB and when
> storeBlobContentMD5 and Client-Side Encryption are disabled.
> * getQualifiedUri() has been deprecated for Blobs. Please use
> getSnapshotQualifiedUri() instead. This new function will return the blob
> including the snapshot (if present) and no SAS token.
> * getQualifiedStorageUri() has been deprecated for Blobs. Please use
> getSnapshotQualifiedStorageUri() instead. This new function will return the
> blob including the snapshot (if present) and no SAS token.
> * Fixed a bug where copying from a blob that included a SAS token and a
> snapshot ommitted the SAS token.
> * Fixed a bug in client-side encryption for tables that was preventing the
> Java client from decrypting entities encrypted with the .NET client, and vice
> versa.
> * Added support for server-side encryption.
> * Added support for getBlobReferenceFromServer methods on CloudBlobContainer
> to support retrieving a blob without knowing its type.
> * Fixed a bug in the retry policies where 300 status codes were being
> retried when they shouldn't be.
