Create Clone of coin.intra.qt.io to run private instances and testing

At the moment, the only way to do testing on the actual virtualized hardware is to run private instance on Coin master machine which will waste production systems precious resources and might cause interference with production instance http://coin.intra.qt.io:8080/coin/.

Proposal is to create another Cloud server to run private instances on coin-test.intra.qt.io that would have access to CI network and only allow vmbuilder account to run Coin on coin.intra.qt.io server.

We could also consider allowing coin-test.intra.qt.io to have its own opennebula instance and network.
