Fix the framework order for each continuous benchmarking run

The environment variable values used by system services are
not persistent, so any changes to them are lost after services
finish execution. As a result, the framework order was not
toggled properly after each continuous benchmarking run
completed. Instead, use a regular file to keep track of the
order.
