Add PathResolver support in top analysis executable and grid submit example scripts (21.2)
Implemented use of PathResolver in ntupler online executable top-xaod. Made corresponding changes in TopExamples/python/grid.py that will now search for a config file among those installed (DATAPATH) using PathResolver if it is not present directly in the submit dir. The new implementation allows to specify the config file as e.g.: top-xaod TTHbbLeptonic/config.txt in.txt
