When telemetry-operator is creating scrapeconfigs, It'll specify targets in this format <host>:<port>. host can be either a hostname or an IP address. if it's an IPv6 IP address, it needs to be wrapped in "[]" before adding the port, which currently doesn't happen. So we have targets like this in IPv6 environments `1111:222:3333:4444:555:666:7:888:9100`, while they should look like this instead: `[1111:222:3333:4444:555:666:7:888]:9100`

The Prometheus WebUI is showing the following logs:
