Removing plugins

This is just a case of identifying what needs to be removed. Internally, a plugin will be shutdown before it is removed:

// Remove all plugins with this name and which implement this interface
pluginManager().remove("worker_pool_1", IWorkerPool.class);

// Remove all plugins which implement this interface
pluginManager().remove(IWorkerPool.class);

// Remove all plugins with this name
pluginManager().remove("worker_pool_1", null);

As above, we assume the method pluginManager() returns the manager from which we want to remove the plugins.
