Support redirect on http_request resource (close #187)

[hico-horiuchi]

Happy new year 🎉
This is implementation of #187 based on chef/chef/lib/chef/http.rb.

For example:

http_request "/tmp/http_request_redirect.html" do
  redirect_limit 1
  url "https://httpbin.org/redirect-to?url=https%3A%2F%2Fhttpbin.org%2Fget%3Ffrom%3Ditamae"
end
