Move logger initialization before k8s client creation

[ykulazhenkov]

ctrl.Log var contains noop logger until logger instance is
explicitly set with ctrl.SetLogger function

If error happen during k8s client creation it will be not logged
because ctrl.SetLogger is called after.

Move logger initialization step before k8s client
creation to be able to log client initialization errors.
