How reproducible:
100% 

Steps to Reproduce:
1. Register a client system using the generated curl command 
2. Do NOT un-register the system and then run the same curl command again. It will ask to use the --force option. 
3. Run the same curl command with the --force option. 

Actual results:
Do not register the system the second time. 

Expected results:
[1] It should use the option or --force 
[2] Curl command should process any additional parameters supported for subscription-manager.
