When initializing the viewfs, authority will be used as the mount table name to find the mount link configurations. To make the mount table name unique, we may want to ignore port if initialized uri authority contains port number. By default, we will consider port number also in ViewFileSystem(This default value false, because to support existing deployments continue with the current behavior).
