CIME ERP test. This class inherits from RestartTest
This is a pes counts hybrid (open-MP/MPI) restart bfb test from
startup. This is just like an ERS test but the pe-counts/threading
count are modified on retart.
(1) Do an initial run with pes set up out of the box (suffix base)
(2) Do a restart test with half the number of tasks and threads (suffix rest)
