[internal] Add ability to list all node or yarn releases

[jmorrell]

This replaces the nodebin endpoint that lists all releases.

Ex: https://nodebin.herokai.com/v1/node/linux-x64

This is used in our integration tests: https://github.com/heroku/heroku-buildpack-nodejs/blob/master/spec/spec_helper.rb#L56 and needs replacement

Example calls:

❯ ./vendor/resolve-version-darwin list node      
0.10.0 https://s3.amazonaws.com/heroku-nodebin/node/release/darwin-x64/node-v0.10.0-darwin-x64.tar.gz
