Opens a file input stream to download the file using the specified request options and
operation context.
<p>
Use {@link #setStreamMinimumReadSizeInBytes(int)} to configure the read size.

@param accessCondition
An {@link AccessCondition} object that represents the access conditions for the file.
@param options
A {@link FileRequestOptions} object that specifies any additional options for the request. Specifying
<code>null</code> will use the default request options from the associated service client (
{@link CloudFileClient}).
@param opContext
An {@link OperationContext} object that represents the context for the current operation. This object
is used to track requests to the storage service, and to provide additional runtime information about
the operation.

@return An <code>InputStream</code> object that represents the stream to use for reading from the file.

@throws StorageException
If a storage service error occurred.
