fix(typescript): improve default response type (octokit#683)

feat: error on 304s (octokit#673)

304s are only returned if according headers are sent. Caching has to be handled by user

fix: uploadAsset with `file: fs.createReadStream()`

fix: respect NO_PROXY environment variable (octokit#667)

breaking: remove `.get{Scope name}Api()` methods

BREAKING CHANGE: `.get{Scope name}Api()` methods have been removed.

Before you could do this

```js
const reposApi = github.getReposApi()
```

Which is the same as doing

```js
const reposApi = github.repos
```

So we removed it :)

feat: add child team list route (octokit#664)

fix: whitelist X-GitHub-SSO header in response (octokit#663)

fix: calculate content-length correctly for raw markdown request

fix: don’t pass `filePath` as query parameter

fix(package): update follow-redirects to version 1.2.6
