Mark all time events ServicePing metric as broken

Manage events metric calcualted for all time, time fram takes over 40
hours to complete for gitlab.com, this is almost 4 times as all the
other metrics combined, this creates a risk of preventing
service ping reporitng process to complete on time. Therfore this
metric is marked as broken and excluded from reporting
