Feature: Calculates default thread pool sizes for EAP7 based on Artemis configuration formulae( https://github.com/apache/activemq-artemis/blob/master/artemis-core-client/src/main/java/org/apache/activemq/artemis/api/core/client/ActiveMQClient.java ) and container limits specified by cgroups. Reason: The JVM is not cgroup aware and therefore cannot be trusted to generate default values for Artemis threads pool arguments. Otherwise, the JVM might calculate thread pool values that are too large for a container with restricted resources to handle. Result: Default Artemis thread pools sizes are calculated based on the resource limits of the container and not of the JVM
