Support Process Removals

[epociask]

Problem

Existing DAG implementation only supports component/edge addition. This is works great for bringing new pipelines on-board but doesn't allow for removal of temporary pipelines (backtests). Additionally in the future, once a user opts to remove an invariant, the corresponding pipeline to it should be removed as well (if applicable).

Problem Solution

Add removal functionality to support the deletion of both edges and components.

Acceptance Criteria

I. removeEdge and removeComponent functions are fully implemented (There may need to be other functions added to support this logic)
II. Unit tests exist that comprehensively assess the behavioral assumptions of each function
III. PoC exists that showcases edge addition/removal using real-time components
