Vhost alias
It would be nice to have an optional 'alias' in vhost config.
Now, if I have an Apache vhost with a ServerName and a ServerAlias, I need to configure two different vhosts in LL::NG config. This is not optimal for memory (the same functions are compiled twice in mod perl's memory) and for management (these vhosts may diverge).
An "Alias" option would meet this need.
It would also partially meet the need of vhost copy/paste expressed in ##542 (closed) and ##227 (closed) (partially = as far as the vhost configs remain the same). Indeed, no matter if the main vhost's name and the aliases are served by different Apache vhosts or by different servers.
Finally, it would be nice to set a regexp as alias, for example wiki-\w+.example.com instead of n alias "wiki-foo.example.com", "wiki-bar.example.com", ...
