This changes `from django.utils.importlib import import_module` to
`from importlib import import_module`, as `django.utils.importlib` will
be removed in django version 1.9.
* Add Optional where required.
* Set type of req_redis_key as `(text_type) -> text_type` for consistency.
Almost all our cache keys and redis keys use this signature.
Currently this uses a Union type for connection_id; we need to figure
out what actually sets that and what its type is and fix that later
(see https://github.com/zulip/zulip/issues/896).
This fixes an exception where client_id was never set in an error code
path. It shouldn't be needed, but I think this makes the code clearer
and this will help in debugging the actual problem.
Related to #753.
django commit 596564e80808 stores the user id in the session as a
string, which broke our code that extracts the user id and compares
it to the id of a UserProfile object.

There will be browser errors on staging when this is deployed due to the socket
protocol changing.

I believe there may also be others. I'm still not sure why clients would be
sending open requests without session or csrf values in their cookies, though.

We also now separate out the times for the socket overhead, the
request service time, and the queuing delays.
(imported from commit e1683f7f28b968b86ebb701b0ac29b00ac6d67c3)
One quirk here is that the Request object is built in the
message_sender worker, not Tornado. This means that the request time
only counts time taken for the actual sending and does not account
for socket overhead. For this reason, I've left the fake logging in
for now so we can compare the two times.

This will hopefully help with the send dialog being stuck on
"sending" as well as allowing us to not show errors to the user on
reconnect.

Clients can only have one connection at a time, anyway, so we can
just keep track of a client id, instead. This makes reconnections
easier.
It's a little funny to use queue ids for the client id, but we know
they should exist by the time the client is connecting and they are
guaranteed to already be unique and authenticatable. We will also
eventually be integrating the event system and the socket code closer
anyway.

The register_json_consumer() function now expects its callback
function to accept a single argument, which is the payload, as
none of the callbacks cared about channel, method, and properties.
This change breaks down as follows:
* A couple test stubs and subclasses were simplified.
* All the consume() and consume_wrapper() functions in
queue_processors.py were simplified.
* Two callbacks via runtornado.py were simplified. One
of the callbacks was socket.respond_send_message, which
had an additional caller, i.e. not register_json_consumer()
calling back to it, and the caller was simplified not
to pass None for the three removed arguments.

Because our authentication system reads cookies from the initial
connection attempt, several SockJS transports can't be used.

New dependency: sockjs-tornado
One known limitation is that we don't clean up sessions for
non-websockets transports. This is a bug in Tornado so I'm going to
look at upgrading us to the latest version:
