Revert to using Chef 11.6.2 due to CHEF-4725

Chef 11.8 on Virtualbox buffers all output until the run is finished, us 11.6.2
until this is fixed. See https://tickets.opscode.com/browse/CHEF-4725
Use apache instead of nginx for now due to some issues with php-fpm configuration.
Install database, server and web in right order so the agent will come up.
