NetworkPkg: Display HTTP redirection info to the screen if need.

HTTP defines a set of status code for redirecting a request to a different URI
in Section 6.4 of RFC7231 and also RFC7583. This patch updates the HTTP boot
driver to display the redirection info to the screen so the user would have
chance to know new URI address of the HTTP boot image.
