Test Info:

// META: global=window,worker
// META: script=../resources/utils.js
// Creates a promise_test that fetches a URL that returns a redirect response.
//
// |opts| has additional options:
// |opts.body|: the request body as a string or blob (default is empty body)
// |opts.expectedBodyAsString|: the expected response body as a string. The
// server is expected to echo the request body. The default is the empty string
// if the request after redirection isn't POST; otherwise it's |opts.body|.
// |opts.expectedRequestContentType|: the expected Content-Type of redirected
// request.
