make AppFlow work with legacy rack
|Assignee:||Daniel Molina||% Done:|
|Target version:||Release 4.2|
|Affected Versions:||OpenNebula 4.2|
Currently for old distributions where rack = 1.1.0 and sinatra = 1.0, there is a "stack level too deep" error because the "settings" variable is referenced used in a scope that doesn't work with old versions. This should be patched so it works with any rack version.
