Error on boot up from celery/Redis

[jlfwong]

When I run make local inside the Docker container, I get this:

[2016-06-27 19:46:39,990: ERROR/MainProcess] Unrecoverable error: TypeError("__init__() got an unexpected keyword argument 'socket_connect_timeout'",)                                              [2/1884]

Bootup seems to continue normally, but I haven't checked yet to see if Redis or Celery is actually working inside the container.

We should be able to fix this by pinning the Redis version used int he container. The server uses 2.6.3, so ideally we use that.
