* Rename from community.kubernetes to kubernetes.core
This goes through and renames community.kubernetes to kubernetes.core.
Most of this was generated from the downstream build script that was
used on the community repository, plus whatever hand edits I could find
that were needed.
The downstream build and test process has also been removed as this
repository is now the downstream repository.
* Fix CONTRIBUTING.md
User can combine multiple resources in the given template
file, which can be consumed by k8s module to create multiple
resources at once.
Fixes: #243
