Example of monitor hostname not allowed

[CommanderStorm]

Monitoring *.tum.sexy make sense for DNS, but don't for the other monitors I think.

What does for example HTTP *.google.de mean?
According to curl, this is an invalid URL.

=> I think we need to limit this to dns, or is there another of the usage of hostNameRegexPattern

Actually good question. Also, DNS' hostname should not accept IP addresses, but the current regex accepts it.

I am thinking maybe we can migrate it to validator for DNS type.
validator.isFQDN() with allow_wildcard: true
