Stubbing Cookie/s with Typhoeus

[erwanlr]

Unless I am doing something wrong, it's currently not possible to stub Typhoeus requests with cookies.

stub_request(:get, url)
  .with(headers: { 'Cookie' => 'key=value' })
  .to_return(body: 'Cookies Accepted!')

does not work because Typhoeus does not set the Cookie header it seems, but rather use the :cookie option (https://github.com/typhoeus/ethon/blob/c5c9c6e10114c9939642be522ab05432ca7ec5d2/lib/ethon/curls/options.rb#L340):
