Before implementing the promotion-conditions(Self and Manual Conditions), it seems necessary to build new abstract/classes for the following existing classes.
For readability ease all these classes are being added by the word "Pipeline" as their prefix.
Three new analogous classes are being made retaining some of the original functions and will timely be updated as other classes start depending on them.
- The classes are created, and they can be used in further APIs. There is is no user-facing feature for now
- The classes are marked as Restricted so that they not a part of API. It will change eventually
- There is basic test automation that these classes really work
