Removed loading of Attract server from the master branch.

Development of Cloud with Attract enabled has been moved to the
'with-attract' branch, so that we can deploy onto production without
Attract enabled.
Once we decide it's time to deploy together with Attract, we can merge
the 'with-attract' branch back to master.
