Retrieves the current {@link FileServiceProperties} for the given storage service. This encapsulates
the CORS configurations.

@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 A {@link FileServiceProperties} object representing the current configuration of the service.

@throws StorageException
If a storage service error occurred.
