* remove unused code
I've removed the provider-specific code under registry, and unused nil
backend, and replaced a call to helper from backend/oss (the other
callers of that func are provisioners scheduled to be deprecated).
I also removed the Dockerfile, as our build process uses a different
file.
Finally I removed the examples directory, which had outdated examples
and links. There are better, actively maintained examples available.
* command: remove various unused bits
* test wasn't running
* backend: remove unused err
Previously this lived in a separate repo docker-hub-images, shared with
other products. Having multiple products sharing a repo complicates
release processes and works against some assumptions made by the Dockerhub
build system.
The "full" Dockerfile contains a Terraform binary built from source, and
so it can be used with any arbitrary Terraform source tree. This doesn't
yet include the "light" Dockerfile, which instead makes an image from
official binaries already on releases.hashicorp.com. That will follow in
a subsequent commit.
