* downgrade go-difflib and go-spew to tagged releases
commit d35edbf80d updated these dependencies
to untagged versions. The diff in both dependencies show that there's no
code changes, and it's unlikely for those modules to do new releases.
Unfortunate, because of that change all projects depending on kubernetes
or any of it's modules now had to upgrade to unreleased versions of
these.
This patch reverts those updates (but it may take some time before
all other projects can be reverted).

Injection
This is an example of implementing an injection function.
This example is written in go and uses the kyaml libraries for parsing the
input and writing the output. Writing in go is not a requirement.
Function implementation
The function is implemented as an image, and built using make image.
The template is implemented as a go program, which reads a collection of input Resource configuration, and looks for invalid configuration.
Function invocation
The function is invoked by authoring a local Resource
with metadata.annotations.[config.kubernetes.io/function] and running:
kustomize build --enable-alpha-plugins local-resource/
This exits non-zero if there is an error.
Running the Example
Run the validator with:
kustomize build --enable-alpha-plugins local-resource/
This will add resource reservations to the Deployment. Change the tshirt-size
annotation from medium to small and rerun:
kustomize build --enable-alpha-plugins local-resource/
Observe that the reservations have changed.
