Jouni Malinen 077f13c3e1 tests: Move parallel-vm.py test control to the host
This allows all VMs to be used at the end of a test sequence by
assigning test cases to VMs based on which VM is available for a new
test case rather than splitting the full task at the beginning and
potentially getting stuck with the last VM running long test cases for
significantly longer than another VM that gets shorter duration tests
assigned to it.
