[Note]: Pipeline Steps are not incorporated in this task.

PromotionBadge class is to be made pipeline compatible:

Required changes during the course:

• Refactor the PromotionBadge class
• Make a new interface analogous to Promotion.java
• Refactor both ManualCondition and GroovyCondition which are the implementations of buildEnvVars
• There is a "addPromotionBadge()" pipeline step which demonstrates the compatibility
• There is is a documentation sample which shows how to use the feature in Pipeline

 Acceptance Criteria:

• Refactor the PromotionBadge class for pipeline compatibility.
• Changes made to Groovy+Manual Condition for binary compatibility.
• Changes made to Promotion and Status classes for binary compatibility.
• Introduction of a new Interface PromotionRun.
• Add the "AddPromotionBadge" class for checking on-spot.
• Unit/Compilation Tests before Merge.
