If my cluster is not reachable I get a "Fatal IDE error"

[adietish]

Steps:

1. ASSERT: make sure that the cluster for the current context is not reachable
2. EXEC: launch IDE and open OpenShift toolkit window (you can also, if you have 2 contexts, switch to the unreachable context using intellij-kubernetes)

Result:
you get a "Fatal IDE error" reported.
The stacktrace is something similar to the following:

java.io.IOException: Process exited with an error: 1 (Exit value: 1) {
	"message": "unable to list all dynamic resources required to find components: failed to fetch api groups from kubernetes: Get \"https://api.akundu-221120231226.devcluster.openshift.com:6443/api?timeout=32s\": dial tcp: lookup api.akundu-221120231226.devcluster.openshift.com on 10.2.0.1:53: no such host"
}
