HADOOP-16294: Enable access to input options by DistCp subclasses.

Browse Source 
Adding a protected-scope getter for the DistCpOptions, so that a subclass does
not need to save its own copy of the inputOptions supplied to its constructor,
if it wishes to override the createInputFileListing method with logic similar
to the original implementation, i.e. calling CopyListing#buildListing with a path and input options.
