Append text to BlobItem in Azure BlobStorage SDK Java V8

The point was that Append could not be done unless the BlobItem TYPE was created as an APPEND BLOB.

		String containerName = "{yourContainerName}";

		try {
			// Parse the connection string and create a blob client to interact with Blob
			// storage
			storageAccount = CloudStorageAccount.parse(storageConnectionString);
			blobClient = storageAccount.createCloudBlobClient();

				//Error if BLOB TYPE is not Append Blob
				// Error returned from the service. Http code: 306 and error code:
				// IncorrectBlobType
				cab.appendText("Hello " + new Date() + "\n", "UTF-8", null, options, null);
