s3_file fails to load instance profile when ENV['http_proxy'] is set.

[grosendorf]

When http_proxy is set in a node's client.rb, the s3_file provider fails to load the instance profile. It instead loads the proxy's instance profile (if it exists), otherwise is raises the following ArgumentError
No credentials provided and no instance profile on this machine.

looks like it doesn't respond no_proxy

I made the following change in s3_file/libraries/s3_file.rb
