Andrew Szeto b312001fd9 rabbitmq: Set a short TCP keepalive idle time on BlockingConnection. ...

The code comment explains this issue in some detail, but essentially
in Kubernetes and Docker Swarm systems, the container overlayer
network has a relatively short TCP idle lifetime (about 15 minutes),
which can lead to it killing the connection between Tornado and
RabbitMQ.

We fix this by setting a TCP keepalive on that connection shorter than
15 minutes.

Fixes #10776.
