DPL: Introduce dangling edges context

[aalkin]

Renames AnalysisContext to a more generic DanglingEdgesContext, used to decide on topology adjustment for a workflow.

This context is now propagated to configuration and initialization context, so that aod-spawner and aod-index-builder can be even more generic. It also permits to delay loading of plugins to set the processing callbacks for aod-reader, aod-spawner, aod-index-builder and aod-ccdb to the adjustTopology stage that only happens on wokrflow deployment, and is itself provided by ArrowSupport plugin, potentially reducing memory usage.
