This extracts function which was used in upgrade/convert flows to retry transient errors to the main `kubernetes` package, expands it to ignore timeout errors, and it is now used to retry errors where applicable in `pkg/kubernetes`. Fixes #3403 Signed-off-by: Andrey Smirnov <smirnov.andrey@gmail.com>
