Fix problem with writing SWM’s CRs

Copy the most recent version of SWM’s CRDs as a workaround for importing QoS Scheduler. The module’s name is now the one used by QoS Scheduler and rerouted via file “go-mod” to folder “internal” that holds the packages needed for Scheduler’s API. The copy avoids the need to access another repository.

The controller’s test suite has a test that verifies that nore recommendation of an SWM application’s workloads can by saved to the database and written back.

Closes #25 (closed)
