Go Exceptions completion

[faust64]

The Kubernetes API server may throw exceptions that would not be caught by that plugin.

A concrete sample would be to deploy FUSE on OpenShift, with NetworkPolicies.
If said NetworkPolicies prevent the k8s API server to communicate with some Jolokia service, then we would find a trace in the API server logs.
That traces starts with a goroutine <int> ..., with no prior mention of a "panic" or "http: panic".
