> testContainerUpdateExecTypeGuaranteedToOpportunistic waits for the container
> to be running before it sends container update request.
> The container update is handled asynchronously in node manager, and it does
> not trigger visible state transition. If the node manager event
> dispatch thread is slow, the unit test can fail at the the assertion
> {code} Assert.assertEquals(ExecutionType.OPPORTUNISTIC,
> status.getExecutionType());{code}
