More descriptive TODOs
Removed code section to check if connection is from hanlon server
Fixing issue where the server config could be pulled from outside the hanlon server
Adding spec http helpers
A new module (SpecHttpHelper) has been added to facilitate robust error handling.  When tests fail, the output will be more descriptive of the error such as 'Unable to reach Hanlon server' or 'DB might be down'.  Additionally, variable declarations have been added to the top of each spec.

The spec_http_helper.rb looks very similar to the http_helpers.rb in ProjectHanlon, however the entire api response is not returned through that module.  It is important to have the entire response to fully test what is returned by the API

Update to use ProjectHanlon::HttpHelper

HttpHelper has been updated to provide the entire http response for use in rspec tests.  The relavent tests have been updated to use ProjectHanlon::HttpHelper instead of the spec_helper.

Additional code corrections too.
