• ITS tracking (GPU): unify usage of vertexer+tracker into a single interface, shared between its-reco-workflow and gpu-reco-workflow
• Now: migrating ITS GPU vertexer:
  • To use the externally-provided GPU allocator (this might also end up in better memory usage thanks to the possibility of allocating different-sized buffers at each set of rofs)
  • Check 1:1 consistency in deterministic mode
  • Make it default in GPU reco (not used currently since the priority was to get 100% consistency in the tracker)
