Missing log message when loadInClusterConfig fails

[maciej-karas-form3]

Problem

Errors in loadInClusterConfig are swallowed entirely.

Context

The problem was discovered when the custom controller was deployed that did not have access to Service Account token or it was not mounted properly due to automountServiceAccountToken: false setting. This caused the function InClusterConfig to fail with token volume not found, but the error was swallowed. After that we still proceed with default location lookup which then fails with misleading error message:

unable to get kubeconfig: invalid configuration: no configuration has been provided, try setting KUBERNETES_MASTER environment variable
