Log wrong webhook url error.

[timdevlet]

Hello. I need to count all errors with Prometheus. Imagine you have a domain in CompositeController.

  hooks:
     sync:
       webhook:
         etag:
           enabled: true
         url: https://domain.com/sync?foo=bar
   parentResource:

If you have the wrong parameter https://domain.com/**sinc** (sinc VS sync) this query can log this:

sum by (cluster, domain, code, instance) (rate (metacontroller_sync_requests_total {cluster=~"$Cluster", domain=~"$Domain", instance=~"$Instance", **code**!="200"}[10m] ) ) > 0

But if you have an error in the domain name ( wrongdomain.com VS domain.com), the error doesn't store in the metacontroller_sync_requests_total.

I can't catch this behavior (invalid domain name in webhook) and track it down.

in my opinion we need a simple mechanism to count all errors that we see in the logs.
