* Script that determines the sharded tests for the current CircleCI container. CircleCI starts
* multiple containers if the "parallelism" option has been specified and this script splits up
* the integration tests into shards based on the amount of parallelism.
*
* It's also possible to manually specify tests which should run on a container because some
* integration tests are more complex and take up more time. In order to properly balance the
* duration of each container, we allow manual test shards to be specified.
*
* The output of this script can then be used to only run the tests which are assigned to the
* current CircleCI container.
