Reserved for internal use. Constructs an HttpURLConnection to perform an update operation.

@param rootUri
A <code>java.net.URI</code> containing an absolute URI to the resource.
@param tableOptions
A {@link TableRequestOptions} object that specifies execution options such as retry policy and timeout
settings for the operation. Specify <code>null</code> to use the request options specified on the
{@link CloudTableClient}.
@param queryBuilder
The {@link UriQueryBuilder} for the operation.
@param opContext
An {@link OperationContext} object for tracking the current operation. Specify <code>null</code> to
safely ignore operation context.
@param tableName
The name of the table.
@param identity
A <code>String</code> representing the identity of the entity. The resulting request will be formatted
using <em>/tableName(identity)</em> if identity is not >code>null</code> or empty.
@param eTag
The etag of the entity.
@return
An <code>HttpURLConnection</code> to use to perform the operation.

@throws IOException
if there is an error opening the connection.
@throws URISyntaxException
if the resource URI is invalid.
@throws StorageException
if a storage service error occurred during the operation.
