Client returns an *http.Client using a default urlfetch Transport. This
client will have the default deadline of 5 seconds, and will check the
validity of SSL certificates.
Any deadline of the provided context will be used for requests through this client;
if the client does not have a deadline then a 5 second default is used.

Transport is an implementation of http.RoundTripper for
App Engine. Users should generally create an http.Client using
this transport and use the Client rather than using this transport
directly.
RoundTrip issues a single HTTP request and returns its response. Per the
http.RoundTripper interface, RoundTrip only returns an error if there
was an unsupported request or the URL Fetch proxy fails.
Note that HTTP response codes such as 5xx, 403, 404, etc are not
errors as far as the transport is concerned and will be returned
with err set to nil.
