Mode 1587 - Updated the ModeShape kit so that it works with AS 7.2.0

For the kit/integration tests to be able to build & run, one needs do a _mvn install -Prelease_ locally, on an AS 7.2.0.Final project.

For users to still be able to build ModeShape without problems, the AS7 kit modules have been moved from the standard build list and into dedicated profiles: integration, assembly, performance.

This PR contains an additional commit, which cleans up/changes IPv4 and IPv6 system properties usage, as it turns out they can have a significant performance impact.
