[MINOR] config: support passing multiple "domain" statements to cookies

In some environments it is not possible to rely on any wildcard for a
domain name (eg: .com, .net, .fr...) so it is required to send multiple
domain extensions. (Un)fortunately the syntax check on the domain name
prevented that from being done the dirty way. So let's just build a
domain list when multiple domains are passed on the same line.
