How to fix supervisor

Version 3.0.0 shipped with an incorrect version of the supervisor configuration. The symptoms are an a failed upgrade to 3.0.1.

Am I affected?

If you run supervisorctl status and you get an error about a missing socket file unix:///var/run/supervisor.sock, you are affected.

How do I fix it?

This will stop supervisor, so if you're running more that datadog-agent in supervisor, please note that all supervised programs will be shut down and restarted.

1. Remove the first 6 lines of /etc/supervisor/conf.d/ddagent.conf that read like the lines in red in this commit.
2. sudo service supervisor stop
3. sudo service supervisor start
4. To verify run supervisorctl status; you should see datadog-agent:* running.

You should be now able to upgrade.
