Request the engine to stop firing rules. If the engine is currently firing a rule, it will finish executing this rule's consequence before stopping.

This method will not remove active Matches from the Agenda. In case the application later wants to continue firing rules from the point where it stopped, it should just call org.kie.api.runtime.KieSession#fireAllRules() or org.kie.api.runtime.KieSession#fireUntilHalt() again.
