Add a custom config field for setting custom domain aliases for client domains

[TGates71]

Add a custom field (Domain Manager?) where a client has the ability to customize their domain's vhost 'ServerAlias' setting.

@TGates71 Correct me if I'm wrong. Can't this be achieved in users vhost directory with .htaccess file? They should be able to add an alias in there. I may be wrong.

yes, I believe so. But most clients will not have the basic knowledge to use a .htaccess
The idea is to simplify the alias ability for clients.
