HTTP code is 500 which indicates error: server error no resources available to schedule container

Before you needlessly scale out, lets make sure this is a valid alert.

1. setup swarm for delta (https://github.com/CodeNow/devops-scripts/wiki/Swarm-Setup)
2. run docker info 2>&1| grep -B5 "org=ORG_ID" | grep "Mem" where ORG_ID is github org id

output should be like

  └ Reserved Memory: 8.106 GiB / 8.187 GiB
  └ Reserved Memory: 0 B / 8.187 GiB
  └ Reserved Memory: 6.109 GiB / 8.187 GiB
  └ Reserved Memory: 7.495 GiB / 8.187 GiB
  └ Reserved Memory: 5.588 GiB / 8.187 GiB
  └ Reserved Memory: 3.725 GiB / 8.187 GiB
  └ Reserved Memory: 3.725 GiB / 8.187 GiB
  └ Reserved Memory: 0 B / 8.187 GiB

left number is how much memory is allocated, right is how much memory is available. scale out only if there is no available memory on all of the lines. ignore the alert if there is room, it was just a swarm glitch
