Handle duration metrics
Merge branch 'r2276-folsomite_duration_metrics'
temporarily increase restart intensity

We are seeing crashes in our production environment of this kind:

** Generic server folsomite_server terminating
** Last message in was {timeout,#Ref<0.0.7.111011>,'#flush'}
** When Server state == {state,60000,
                               [folsomite,"crtt_hfb"],
                               "crtt_hfb_ip-10-48-186-135","crtt_hfb",
                               #Ref<0.0.7.111011>}
** Reason for termination ==
** {badarith,[{bear,harmonic_mean,1,[]},
              {bear,get_statistics,1,[]},
              {lists,unzip,1,[]}]}

Until we have found this bug we are making sure the whole sup isn't
terminated.
