Get resumes

This allows us to use the new Resume GET api that has been created via the Ruby-API-Gem.  This has 100% line coverage for all lines added.  
I feel like you are adding lines and a method for this for no reason. If you are going to set @api_args = args and take that line you might as well just replace it with 
````ruby
response = Cb.configuration.uri_resume_get.gsub(':resume_hash', args[:resume_hash])
Cb::Responses::Resumes::ResumeGet.new response
````
