commands_post should have option to run after SIGINT #3858
Description
When a SIGINT (Ctrl-C) happens during test run, commands_post is not run, leaving no chance for cleanup.
Current behavior is by design, but an opt-in flag to always run commands_post (even after SIGINT) would be useful. Multiple users have requested this.
Suggested approach: add a flag like commands_post_always = true or similar, where first Ctrl-C interrupts commands and second Ctrl-C interrupts commands_post.
