Addition of restrictPropagationThroughHierarchy flag in classification propagation

[hr2904]

Change description

Currently when a tag is propagated, it can be propagated to via a couple of paths
Via hierarchy
Via lineage

When it comes to configure & customize these propagation paths, we only support restricting though lineage with restrictPropagationThroughLineage flag. This means propagations via hierarchy are not optional & done forcefully even when not required.

To make it optional, we have introduced another flag which help to control propagations via hierarchy : restrictPropagationThroughHierarchy
Added Argument of restrictThroughHierarchy in all methods where restrictThroughLineage was being passed, and handled the edge case of both flag being true. Added the concept of toExclude for : flag basis getting of labels.
Handled all test cases and made fixes for them.
Added a method to test propagation config before sending it to Background task queue.
