Debug: Move the config of environment variable to the top of server.js.
When the mothership is loading the winston, it will not find the config of environment variable. Because it have not been set before the winston.
Now, I solved it.
Merge branch 'master' of github.com:SunshineLibrary/mothership
[yanan] release dashboard v2
Merge remote-tracking branch 'upstream/master'
Merge branch 'master' into course-builder
