parallelThreads and invoker.ordinal

invoker.ordinal property in invokerPropertiesFile allow us to control run order of test projects.

Its work as documented when we use only one thread for executing tests.

But we use more than one executing threads jobs are started in the same time on separate threads so ordering of executing is not preserved.

Proposition

Groups jobs by ordinal value and the jobs with the same value can be run concurrently on separate threads.

Next group of jobs should be executed after all previous finished.
