This adds in the legacy docs into the repo and enables automatic deployment via netlify. The netlify-docs.js script will error out the build on netlify on master if we're not on a tagged commit so that it won't redeploy the docs unless there's a new release. If we're not on master or on master with a tagged commit, it will process with the deploy.
Also, this removes the API docs from being published with npm, fixes#4609.
