force proxy off for metadata queries

force proxy off for all metadata queries

[namtzigla]

if you have the following client.rb file:

chef_server_url "https://xxxx.net"
validation_client_name "chef-validator"
http_proxy "http://1.1.1.1:3128"
https_proxy "http://1.1.1.1:3128"
no_proxy "1.*,*.net,169.254.*"
node_name "nfs1.aws.eu"

# set the proxy env variable so rubygems works correctly
ENV['http_proxy'] = "http://1.1.1.1:3128"
ENV['HTTP_PROXY'] = "http://1.1.1.1:3128"
ENV['https_proxy'] = "http://1.1.1.1:3128"
ENV['HTTPS_PROXY'] = "http://1.1.1.1:3128"

no_proxy option is ignored by the recipe, so for all the metadata queries from libraries/ec2.rb I've added :proxy => false option. I belive this is an important option especially for aws vpc environments where you must have a proxy setup.
