Restore missing variables in Redis module

- Add back network_private_subnet_cidrs variable that was accidentally removed
- Move network_id variable to correct position (after tfe_instance_sg)
- Remove duplicate network_id variable at end of file
- Keep only Redis passwordless additions, restore original variable structure
