fixes#270
all errors in undeploy method(both kubernetes and openshift) are appended in a slice of errors,
and then it will be returned after successful deletion of all components.
This commit refactors the code to remove more or less
all occurences of logrus.Fatalf() from the code under
pkg/ except for app.go where all the errors are being
handled currently.
This is being done since random logrus.Fatalf() calls
all around the code was making handling the errors,
unit testing and troubleshooting a bit more painful.
logrus.Fatalf() calls are either replaced by
return errors.New("new error")
or
return errors.Wrap(err, "annonate error")
calls, and the function signatures are accordingly
changed to accomodate the new return values.
The unit tests which previously used to check
if logrus.Fatalf() calls worked fine have also
been fixed to only check for errors now.
Fixes#416
