Sometimes webapps expose services that are consumed by other webapps running on
the same webcontainer. In such a situation, the developer needs the webcontainer
to deploy/initialize applications in a particular order.
At the minimum users should be able to define a top level application like in
Tomcat's ROOT webapp.
Adding this feature will bring feature parity with Tomcat for Glassfish V3
The user should be able to set the initialization priority at deployment time
either using asadmin or using an entry in the sun-web.xml
