Note that this diff does more than just deduplicate code:

• it installs the full RPCServerApp application and use its factory to generate what we manually installed as route endpoints (similarly as the indexer storage did a while back, with no issue that we know ;)
  
  -> doing so though, it drops the metrics computations on those manually installed endpoints (server module)
  
  -> and moves it on the storage.py module. which i don't really know if it's good or bad (it's not deduplication).

• moves the metrics functions into its own module (which is good but this had nothing to do with a deduplication (so a commit aside would be best)

I'm not against this.
My point is more that this should be clearly stated in the description's diff (as a tradeoff, deduplicate server code and moves metrics computations in storage.py module or some such)

Also as the diff is quite big, the module separation metrics should have been in another commit and diff.
That would have reduced a bit that diff (not much though).
