Subject: [PATCH] Clear strategy-driven markers in clearOverlays()

clearOverlays() cleared this provider's own overlay controllers but not
the strategy controller behind MarkerRenderingSupport, so markers drawn
by clustering (or any other marker-rendering plugin) stayed on the map.

It now ends with MapServiceRegistry.clearMarkerRendering() (ios-sdk-core
fix/clear-strategy), which reaches the registered support's
clearMarkers(): StrategyMarkerController.clear() (onRemove ->
strategy.clear() -> onPostProcess), and the next syncMarkers sends the
markers again, as the overlay collectors do after a clear.

Requires the ios-sdk-core change that adds clearMarkers() to
MarkerRenderingSupport.
