Should we have a new condition for power? Because this is only targeting mac,
while I guess it should also target android when power measurement is available.

I've wanted this feature too in many contexts. There are a whole range of
capabilities that would be nice to check. But I'd recommend we file a bug and
not hold up this CL for it.

+class ManyTabs(test.Test):
+  """Load 5 blank tabs and measure power usage."""
+  tag = 'many_blank_tabs'
+  test = power_many_tabs.PowerManyTabs
+  page_set = 'page_sets/blank_page.json'
+  options = {'pageset_repeat_iters': 5}
