Alter default node and core values for policy runs

Changed the default node and core values to increase parallelization and runtime for a policy job. Also fix validation for both of those values that was being skipped due to incorrect type checking and lack of parentheses. Type checking for both is performed by argparse automatically so there's no need for it in the validation functions.
