docs: The selectionStrategy given as String argument is selected as locatorSelectionStrategy.
  If selectionStrategy is null, the defaultLocatorSelectionStrategy is used instead.
  Then the new locatorSelectionStrategy is connected to the locatorClient and the matcher.
  A new LocatorTargetSelector is created, set to the locatorSelectionStrategy and then set
  as selector in the conduitSelectorHolder.
