Issue MULE-8146: Grizzly thread leaks
When running the CE test suite, you can see grizzly threads piling up to the point in which by the time the suite is almost over there's a gigantic amount of idle threads. This leads to flakiness and in some environments it even fails the build because the host can't allocate more threads. Additionally, it raises the concern about those threads being actually stopped when an application is undeployed on a live container. Please trace and fix the leak and verify that those threads do not survive an application undeployment.
