Metatron Discovery 3.3.0 rc2

Enhance displaying the resources associated with the item in the workspace (#2167)

From now on, you can view whole information from the main page of your workspace. Along with some design changes, let you know the (un)publishing status of the resources associated with the item. Your authorization, errors, language you use in Notebook, and type of data connection for Workbench are graphically added to show you in one page.

Improve Java version 12 compatibility (#1704)

We officially suggest jdk 8, but need to support upper versions. If you are jdk 11 or 12 user, then use Metatron Discovery with no need to install jdk 8.
