Hide wen_restart and do not take default value for now.

--wen_restart not ready yet, hide it for now and do not take default value so not to break wait_for_supermajority.

From the initial PR, I see that you added the arg but didn't actually connect it to anything. Ie, nothing in solana/validator/src/main.rs actually reads the wen_restart arg. More so, the field is not set in ValidatorConfig struct that is passed to Validator::new(). So, ValidatorConfig will just populate that field with its' default which is None.

I'm fine just marking this hidden for now, but arguably adding to the CLI could have waited until things were fully plumbed (unless not plumbing it down was an oversight).
