Client support for HTTP redirects (301, 302, 303, 307, 308)

[ethanndickson]

Any and all requests made by the client currently do not handle redirects.

[ethanndickson]

Our client should, ideally, use a higher level HTTP library, such as reqwest, which would handle things like HTTP redirects.

Unfortunately, with rust-tls unavailable for use, reqwest would have to use rust-native-tls, which, although it uses openssl on Linux, does not expose a way to modify the cipher list.

If rust-native-tls were to ever expose a way to modify the openssl cipher list, and then this be further exposed by reqwest, we would reasonably be able to switch from Hyper to reqwest at least for the core client functionality.
