This fixes some scope isses that were introduced by shadowing vars inside anonymous functions as well as using a naked return.
Fixed by using unique err names and explicitly returning errors.
Additional improvement is using the HomeDir() util function provided by client-go instead of including a helper function at the bottom of this example.

This updates the create-update-delete-deployment example with the following:
Make use of client-go retry util in Update() steps instead of simple for loops.
Using RetryOnConflict is generally better practice as it won't become stuck in a retry loop and uses exponential backoff to prevent exhausting the apiserver.
Instead of changing annotations to demonstrate Updates/Rollbacks, change the container image as it is less confusing for readers and a better real-world example.
Improve comments and README to reflect above changes.
