DescribeTag action is missing

[dewvow]

Hi, I'd like to use this cookbook to describe (query) AWS tags, but there's no "describe" action.

Actions:

add - Add tags to a resource. update - Add or modify existing tags on a resource -- this is the default action. remove - Remove tags from a resource, but only if the specified values match the existing ones. force_remove - Remove tags from a resource, regardless of their values.

You can get that by doing the same query at the bottom of providers/resource_tag.rb:

https://github.com/opscode-cookbooks/aws/blob/master/providers/resource_tag.rb#L89-L91

Should be trivial to make a method for that, and submit a Pull request ;)
