Description

As today when a view is acquired it is also automatically started and never stopped until the service it belongs to is stopped, there should be a way to stop start/stop views according to effective usage.

// get and increase reference
CamelClusterView view = clusterService.getView("...");

// release the view and stop it when ref count is zero.
boolean released = clusterService.releaseView(view);
