What this PR does / why we need it:
Right now the test was directly using os.Stat accessing the filesystem. That's not good idea in unit tests - then it cannot be run in an environment without .kubeconfig at the expected location.
One option I was investigating was using https://github.com/spf13/afero but then I decided to go with no extra dependencies and just refactored the code and test to not use the filesystem.
