Sync coming soon status from WPCOM to LYS.

When clicking on Launch site button in https://wordpress.com/settings/general/SITE_URL When changing the following states in https://wordpress.com/settings/general/SITE_URL:

• Live - LYS should be set to live
• Coming soon - LYS should be set to coming soon
• Private - No change to LYS state, but frontend page should prompt wp-admin login

This PR doesn't sync the initial coming soon state from WPCOM. I think we need to see when WPCOM set the initial coming soon state to decide how to handle it.
