[BEAM-1319] Add conflict resolution to the PipelineOptions internal
argparse.
In some instances where a PipelineOptions subclass was defined in the
main session and save_main_session option is enabled, that subclass may
appear multiple times in the PipelineOptions.__subclassess__() list.
This is causing problems with the argparse because options are not
unique any more.
This change filters the subclasses by name, and pick the last unique
instance of each subclass.
