LPS-48408 As a system administrator I'd like to be able to take cluster wide thread dumps to help support diagnose my problem

Hi Tina,

Eventually, I chose to rename the method not the class (https://github.com/laszlocsontos/liferay-portal/commit/61ad9ce273844dfab417a784a1b83c5f7af4012b) and deprecated the original method. We might not know if someone has been using ThreadUtil from plugins.

Thanks for reviewing!

Cheers,
László

PS: Please let me know if you spot anything else I should change.
