Control center should select cipher strength by customer.

Some user wants to use high-strength ciphers to adjust their own security guideline. And some others also wants to keep backward compatibility.
If these command is available, SMG can follow each customer's environment.
(example)
cc-config --cipher high
cc-config --cipher medium
cc-config --cipher low
cc-config --cipher default
If these configuration is available for MTA, it will be more happy.
