We are planning to add startup tests that start up to things other than the
blank page, so I do think it would be appropriate to keep blank_page in the
names.

Done.

   test = startup.Startup
   page_set = 'page_sets/blank_page.json'
   options = {'cold': True,
              'pageset_repeat_iters': 5}
 
 
-class StartupWarmBlankPage(test.Test):
+class StartupWarm(test.Test):
+  name = 'warm'
   test = startup.Startup
   page_set = 'page_sets/blank_page.json'
   options = {'warm': True,
              'pageset_repeat_iters': 20}
