v-add-web-domain

#!/bin/bash
# info: add web domain
# options: USER DOMAIN [IP] [RESTART] [ALIASES] [PROXY_EXTENSIONS]
#
# example: v-add-web-domain admin wonderland.com 192.18.22.43 yes www.wonderland.com
#
# This function adds virtual host to a server. In cases when ip is
# undefined in the script, "default" template will be used. The alias of
# `www.domain.tld` type will be automatically assigned to the domain unless
# "none" is transmited as argument. If ip have associated dns name, this
# domain will also get the alias domain-tpl.$ipname. An alias with the ip
# name is useful during the site testing while dns isn't moved to server yet.
