_Optional, Default=```Host(`{{ normalize .Name }}`)```_
For a given application if no routing rule was defined by a label, it is defined by this defaultRule instead.
It must be a valid [Go template](https://golang.org/pkg/text/template/),
augmented with the [sprig template functions](http://masterminds.github.io/sprig/).
The app ID can be accessed as the Name identifier,
and the template has access to all the labels defined on this Marathon application.
