In response to https://linear.app/comm/issue/ENG-497/amqp-connection-lostreconnection-handling

We want to reconnect when the amqp connection breaks. As mentioned in the GitHub issue attached to the linear task, we have to recreate the connection, there's no way to reuse existing resources.

Test Plan:

cd services
yarn run-tunnelbroker-service

Then wait ~20-30mins holding an idle connection, after that time, it'll break and be recreated.
