DATA-reco anchoring and improved configurability

This commit is a step in the direction of being
able to anchor MC workflows to the settings use in
DATA reconstruction passes.

This is achieved via a couple of ingredients:

a) improved configurability of o2dpg_sim_workflow:

   - we can give a json config externally, which
     may include ConfigKeyValues and other keys
     to which the MC workflow creation is sensitive

   - separation of default config creation into extra
     script

   - slight change in the way how tasks declare what ConfigKeyValues
     they need / are sensitive too

   - can now configure list of sensitive detectors
   - can now configure input lists for vertexers and track matcher tasks

b) A script that can parse DPL topologies and parameters from
   a file created by DATA reconstruction, and which creates
   a json config that can be fed to MC workflow creating via a)
