No documentation for context root for app deployed without server.xml config

[scottkurz]

When an application is deployed without a server.xml config element like <webApplication> it will either be deployed into dropins or apps (as doc'd here under the appsDirectory parm).

The context root the app ends up with isn't documented, as far as I can see.

It seems different for dropins (which seems to ues finalName) vs. apps (which uses the artifactId), and these don't dflt to the same thing since finalName default is artifactId-version.

(And maybe if we were doing over we'd have just defaulted to "/" ).

It might help to just say that we generally expect you to set the context root in the server.xml since we don't have much in the way of plugin config.
