Description

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

 Assert.assertEquals(ExecutionType.OPPORTUNISTIC, status.getExecutionType());
