This reports the current lifecycle state (such as running, stopped, or complete) of the throughput portion of an RFC2544/Y.1564 benchmark for the hardware session identified by its test instance, PCP, and color. An admin polls this before trying to read the corresponding throughput results table, because pulling min/max/avg numbers while the state still shows the test in progress would give a partial or misleading figure. For example, an automation script waits until cienaCesBenchmarkGenTestSessionThroughputTestState reports 'completed' before it queries cienaCesBenchmarkGenTestSessionThroughputResultsMax for the final number.
