ARQ should support Multi-module (Multiple WAR deployments) testing

It would be useful if you could return multiple deployments, potentially as a list of archives, and then run tests either AS_CLIENT that would interact against all deployments (however the container handles them,) or run with one deployment as the primary and run tests in IN_CONTAINER from the perspective of that WAR.

This would effectively allow testing of multi-module WAR deployments or large-scale applications that are broken up under different ServletContexts.
