[Blocks v4.0.0] OSGi R6 annotations broke Workflow Process Labels in AEM

[davidjgonzalez]

Required Information

• AEM Version, including Service Packs, Cumulative Fix Packs, etc: AEM 6.4.2
• ACS AEM Commons Version: 3.19.1-SNAPSHOT
• Reproducible on Latest? on 3.19.1-SNAPSHOT (post OSGi R6)

The break appears to be caused by the move to OSGi R6 annotations in #1560

Expected Behavior

ACS Commons Workflow processes should display their human-friendly labels in the process selection drop-down.

Actual Behavior

The WF full class name is displayed in the process dropdown.

Steps to Reproduce

1. Create a new WF Model
2. Add a WF Process Step
3. Goto Process tab
4. Open the Process dropdown list, and all ACS Commons WF's are listed by Java package name (not by process label)

It appears that the process.label is not being registered as an OSGi component property.
