IncludeCredentialsMiddleware

While making an API request using fetch, the cookies aren't included.

While most APIs shouldn't need cookies anyway and use headers to get some request, we want to be able to enable cookies for all requests.

const client = new Client();

client.addMiddleware(new IncludeCredentialsMiddleware("include"));

This simply sets include to mode, it also defaults to include, and if you want to overwrite, you can pass anything you want.

Accepted values are: omit, include and same-origin
