This launcher Allows subclasses to only implement methods they want to override.
Originally, this launcher has been implemented in Custom Tools Plugin, but there are many duplicates in other plugins => it would be useful to have it in Jenkins core.

This change is a follow-up to Executor::isAlive() issues in #1229.

Since 1.536, {@link Executor}s start threads on-demand.
The entire logic should use Executor::isActive() instead of Executor::isAlive() in order to check if the {@link Executor} it ready to take tasks.

Since the change breaks previous executor availability flows, it is required to document changes somehow.
