Host Controller path resources do not result in runtime services

On the HC, the add handler for the host.xml path resources is not installing any runtime services. It just updates the model.

That makes the path configuration data available for use on servers created by the HC, but any services running on the HC itself cannot utilize the path. For example, a security-realm used for the management interfaces that pointed to keystore, trusstore or properties file could not use one of these paths. It could only use the automatically created paths derived from the the HostEnvironment.
