Title: Version 3 fix secgroup case

If I provide the security group "webservice" to the cluster_chef cloud module, and the actual EC2 security group is "Webservice" then knife cluster bootstrap will crash out without a useful message. This patch catches the exception and checks whether case-sensitivity is the issue. If it can find a case-insensitive match, it fixes up the name and allows the bootstrap to continue with a message to the console.
