Migrate to cloudfoundry-samples org

Just discovered https://github.com/cloudfoundry-samples, via #21 (comment).

i.e. we should deprecate the ones that have community-maintained versions elsewhere, then create technology-specific repositories in that GitHub organization for the ones that don't exist yet.

FYI that I just got added to the org, for when we are ready to move stuff. New folks can get added by emailing cf-dev@lists.cloudfoundry.org, per https://cloudfoundry.slack.com/archives/cf-docs/p1474478566000077.

I think this repository has value to new users in that all of the samples are only "Hello World", and they all work. The cloudfoundry-samples has 70 repositories in various states of maintenance, many of which haven't been updated since 2013.

If we do migrate to cloudfoundry-samples I think it should be as a single repo cloudgov-hello-worlds, have tests to ensure deployability, and perhaps merge in https://github.com/cloudfoundry-samples/dotnet-core-hello-world.

Meanwhile, I'd like to keep this running for cloud.gov.
