We current do this as part of send-daily-performance-platform-stats but
now this moves it into its own separate task. This is for two reasons
- we will shortly get rid of the send-daily-performance-platform-stats
task as we no longer will need to send anything to performance
platform
- even if we did decide to keep the task
send-daily-performance-platform-stats and remove the specific bits
that relate to the performance platform, it's probably nicer to
rewrite the new task from scratch to make sure it's all clear and easy
to understand
