Subject: [PATCH] Don't hard-code the 'haf-world' docker-compose prefix in
assisted startup. Reduce the amount of total memory assisted startup requires
before creating a ramdisk to increase the chance that a 64G system will
qualify. Explicitly set a maxconn limit for haproxy to prevent errors when
running on systems where max open file descriptors is set really high
