Detect usage of the Quartz scheduler

This rule flags the presence of the Quartz Job Scheduler in the application. More specifically, it detects anything under the org.quartz package. Due to the creation of unmanaged threads and, consequently, limited access to container resources, using this scheduler is discouraged.

The Quartz scheduler depends on the CommonJ Work Manager API. The CommonJ Work Manager API is provided on WebSphere Liberty Base, ND, and z/OS version 22.0.0.1 and later through the heritageAPIs-1.1 feature. Managed Liberty, Open Liberty and WebSphere Liberty Core do not provide the CommonJ Work Manager API. For more information on configuring the use of the CommonJ Timer and Work Manager APIs in WebSphere Liberty see the documentation for Enabling heritage programming models.
