added new section to text formatter to output a command to rerun all failed tests
requested to merge github/fork/axos88/output_single_command_to_rerun_all_tests_on_2_14 into 2-14-maintenance
Created by: axos88
The new section will include a single (long) command that can be copy pasted to the terminal that will rerun all failed tests in one step.
This is needed for large test suites to fix all braking tests before doing a full run.
