docs: /*
  Indexation goal is to retrieve the array of caches directory. Find all jobID.json file with their IDs,
  and add them into couchDB database.
  @cacheArray : represent the previousCacheDir key content from the config file, which is paths of all cache directory.
  #dataToCouch : array that will contain all jobID.json file that attempt to be add inside the couchDB database.
  #pathResult : list of all jobID.json path found in all caches directory.
