Wait before retrying tests via --rerun-failed flag

Is there a feature available to specify a wait time before retrying tests? This feature could potentially help mitigate failures caused by resource contention in services. Implementing an exponential wait time can be particularly effective in such scenarios, reducing the likelihood of failures.

Start at the command-line handling for --rerun-failed and trace how failed tests are retried. Clarify whether the wait duration and exponential behavior require a new option or defined defaults; done should mean the retry delay is specified and the behavior is covered by tests.
