kamctl: lcr commands disabled

- only left enabled is the one related to weights
- the commands were not using latest db schema
- Juha suggested handling lcr via kamctl is too complex to scale, so
  commands are disabled until new code is contributed
(cherry picked from commit 252fcd963637e92727e58f6c1b84bf06200eee12)
