Re-organize new jet config

This MR re-organize the new jet config.

• rename the classes used to describe jet inputs
• move all the code to solve jet dependencies into a dedicated module DependencyHelper
• move all the code to instantiate the final c++ tools/algs into JetRecConfig
• as a consequence delete and rename several modules
• introduce a new jet context dictionary (see the README for rationale)
• introduce a new simple alg to perform track selection (relying on a standard ID tool) and record them. This is a 1st step toward simplifying the many confusing tools we had to do this
• adapt the trigger config
• add new tests (integrating the previous ones in the new ones)

None of these changes affect the standard reco since the new jet config is not yet in production.
