Currently this script runs a format testing for all the configs that are located in "failure_configs" directory once. However, some of these configs (for example one for https://jira.mongodb.org/browse/WT-14270) reproduce the corresponding issues only once in many executions (for this one, about once every 30 runs). So if test execution doesn’t take much time, it might be useful to run certain tests multiple times in a single session.

It can be done by extending run_format_configs.sh functionality.
