Add DomainAddress premium feature

on GitHub

DomainAddress features behind the PREMIUM_ENABLED flag. When the flag is enabled, a user with premium subscription can set a subdomain under the service's domain and create an email address impromptu (generated when first email received), display new DomainAddress in the dashboard, and manage the DomainAddress on the dashboard. The release also includes backend functionality to randomly generate DomainAddress and create a named DomainAddress.
