with this dynamic url http://$(dig +short @{{ "lxd-host-ip" | lookup }} {{ project }}-{{ stage }}):2501 if dig doesn't return anything, the url resolves to http//:2501, which then fails and creates a heal-check file with a different md5 than intended to prevent that, we can allow the user to specifiy an identifier that will be used instead of the md5 of the url in the filename it will be more readable and more consistent for dynamic urls
