This PR enables ESQL heap attack tests. I have run this suite over 500 iterations with different hardware configurations for the last two days, and all have been successful with the changes in #104159. Additionally, this PR adds an action that can trigger OOM to generate a heap dump if a test takes more than 5 minutes. I've seen cases (previously with our CI) where the test didn't result in OOM but was taking too long. Having the ability to inspect the heap in such cases would be beneficial. Closes #103527 Closes #100678
