Vagrant provisioning fails due to incorrect rack version

[jglamine]

Steps to reproduce:

Run vagrant up The command will fail with:

ERROR:  Error installing chef:
    rack requires Ruby version >= 2.2.2.

This happens because the most recent version of rack requires ruby >=2.2.2, but we're using ruby 1.9.

There are two possible solutions:

• 1. Modify the vagrant script to install an older version of rack. (see https://github.com/phusion/passenger/issues/1710#issuecomment-166472107)

gem install rack -v=1.6.4 --no-ri --no-rdoc
gem install chef -v "11.16.4" --no-ri --no-rdoc

• 2. Wait for a new version of chef and then upgrade. They already have a fix in master, we just need them to publish a new version (see https://github.com/chef/chef/pull/5072).

Right now I'm solving the problem locally using method 1.

Now that we're using ansible instead of chef, this is a non-issue.
