arquillian.xml properties should be injectable in RouteURL annotation

[lordofthejars]

Issue Overview

Expression resolver should be able to resolve this property defined in arquillian.xml if it's used to inject variable in test like @RouteUrl("{app.name}")

Expected Behaviour

Properties defined in arquillian.xml can be injected as @RouteUrl property

Current Behaviour

Not supported

We should look if this functionality of generic key-value config pairs is available in core so we can simply pass it to @RouteUrl provider. If not we should enhance core.
