Install gem before to require it at Test-Kitchen

Context

I was trying some TDD with [Tesk-Kitchen][1] and [ServerSpec][2] when I found myself in the following case scenario:

I have a integration test like this:

# cookbook_webtest/test/integration/default/serverspec/localhost/webtest_spec.rb

I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.

As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

group browsers {
    cpu {
#       Set the relative share of CPU resources equal to 25%
        cpu.shares = "256";
 }

	# cookbook/files/default/pushover_handler.rb

	require "net/https"

	module MyOrg
	class PushOver < Chef::Handler

	def initialize(config={})
	@config = config
	end

	@ECHO ON

	REM This batch script is almost identical to http://code.can.cd/winrm_setup.bat
	REM To use this from powershell on windows in a one liner:
	REM (New-Object System.Net.WebClient).DownloadFile('https://gist.github.com/juanje/8496054/raw/winrm_setup.bat','winrm_setup.bat') ; .\winrm_setup.bat
	cmd.exe /c winrm quickconfig -q
	cmd.exe /c winrm quickconfig -transport:http
	cmd.exe /c winrm set winrm/config @{MaxTimeoutms="1800000"}
	cmd.exe /c winrm set winrm/config/winrs @{MaxMemoryPerShellMB="300"}
	cmd.exe /c winrm set winrm/config/service @{AllowUnencrypted="true"}

	# The command to see the space used under each directory is `du -sh /*`
	# The `2> /dev/null` at the end is to avoid get lost with a lot of minor errors.
	# For the example 'mydockerimage' is the name of the Docker image to be checked.
	# Another way is to use Dive (https://github.com/wagoodman/dive), a really nice tool for this.
