Chris Piraino 0b9ba9660d Validate hosts input in ingress gateway config entry
We can only allow host names that are valid domain names because we put
these hosts into a DNSSAN. In addition, we validate that the wildcard
specifier '*' is only present as the leftmost label to allow for a
wildcard DNSSAN and associated wildcard Host routing in the ingress
gateway proxy.
