Simon Willnauer d1bc099c91 Add multi-node IT infrastructure ... This adds the infrastrucutre to run integration tests with more than one node. * it adds relevant macros and targets to integration-tests.xml to start unicast nodes * there is a qa/smoke-test-multinode project that simulates such a setup this commit is soely the infrastructure and doesn't hook up any projects to use this. For reliability and stability reasons this should be used with care and only if it's really needed. Closes #12718		2015-08-11 11:36:15 +02:00
