The code in pkg github.com/emicklei/examples/ is not referenced in kubernetes
codebase. Somehow it was mirrored in the vendor directory in a previous
PR #25365.
This causes problems for godeps which will then include the reference to this
code in the Godeps.json file (among other packages that are not in the vendors
directory).
Removing the directory and its contents fixes the fissue and we believe the
current godeps process should prevent it from re-occurring.
