/*
 * Stages (aka ramping) is how you, in code, specify the ramping of VUs.
 * That is, how many VUs should be active and generating traffic against
 * the target system at any specific point in time for the duration of
 * the test.
 * 
 * The following stages configuration will result in up-flat-down ramping
 * profile over a 150s total test duration.
