[1.3.7-prepare][Improvement] Impove text description, OSUtilsTest and reduce heap memory for create/upgrade-dolphinscheduler.sh (#5890)

* Rename NORAML_NODE_STATUS to NORMAL_NODE_STATUS

* Fix OSUtilsTest

* Optimize comments in properties

* Reduce heap size to 64m in create-dolphinscheduler.sh and upgrade-dolphinscheduler.sh

* [Improvement][License] Update oshi version in release-docs/LICENSE

* Add test prefix for test method
