* Change Google Cloud module to require the `region` variable * Workers are created in random zones within the given region * Tolerate Google Cloud zone failures or capacity issues * If workers are preempted (if enabled), replacement instances can be drawn from any zone in the region, which should avoid scheduling issues that were possible before if a single zone aggressively preempts instances (presumably due to Google Cloud capacity)
