removed X-Original-URI

 - currently this header isn't handled by ditto
 - if someone were to make a large request with many thingIds in a GET request the X-Original-URI will be passed as a Ditto Header in the protocol message causing a DittoHeadersTooLarge exception -> http error 431
 - reverted kindest to 1.28.0 as images for 1.28.3 are no longer in docker.io
