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.

> As required by [HADOOP-14478], we're expecting the {{BlobInputStream}} to support advanced
{{readFully()}} by taking hints of mark. This can only be done by means of sdk version bump.
