Basis for Cluster integration testing

This branch adds cluster testing via Vagrant.
Requires my branch of the vagrant-maven plugin to work,
which can be sourced here:
https://github.com/parshimers/vagrant-maven-plugin
It is enabled with -DclusterTest=true in mvn verify.
A virtualized cluster with 4 nodes is started, and
then Asterix is started via managix on this cluster,
and then stopped.
