See `simpleTestCases` data type implementation for available configuration for each template.
See `op` data type implementation in [scheduler_perf_test.go](scheduler_perf_test.go)
for available operations to build `WorkloadTemplate`.
Initial pods create a state of a cluster before the scheduler performance measurement can begin.
Testing pods are then subject to performance measurement.

The configuration file under `config/performance-config.yaml` contains a default list of templates to cover
various scenarios. In case you want to add your own, you can extend the list with new templates.
It's also possible to extend `simpleTestCases` data type, respectively its underlying data types
