void	deleteManagedResource(ManagedResource res)	Deletes a managed resource if it is not being used by any Solr components.
ManagedResource	getManagedResource(String resourceId)	Returns the ManagedResource subclass instance corresponding to the given resourceId from the registry.
ManagedResource	getManagedResourceOrNull(String resourceId)	Returns the ManagedResource subclass instance corresponding to the given resourceId from the registry, or null if no resource has been registered with the given resourceId.
void	init(SolrResourceLoader loader, org.apache.solr.common.util.NamedList<String> initArgs, ManagedResourceStorage.StorageIO storageIO)	Initializes the RestManager with the storageIO being optionally created outside of this implementation such as to use ZooKeeper instead of the local FS.
