Implementation of the CIME NCR test. This class inherits from SystemTestsCommon
Build two exectuables for this test:
The first runs two instances for each component with the same total number of tasks,
and runs each of them concurrently
The second is a default build
NOTE: This is currently untested, and may not be working properly
