Response codes are handled as integers, but are strings

[mikesaelim]

Describe the bug
I think Net::HTTP is returning response codes as strings. The call to Net::HTTP.request() here returns a Net::HTTPResponse object, which has a string code: Net::HTTPResponse.

However, it looks like the client handles the response code as if it were an integer, in a number of places. For example, here and here. The FakeResponse in the specs also gets initialized with integer response codes.

If I'm not mistaken, this means 204s and redirects might not be handled properly. If you concur, I'd be willing to submit a PR to fix how the response code is handled.

To Reproduce
Steps to reproduce the behavior:

1. Call a method on the client that calls the Datadog API
2. Observe that the returned response code is a string.

Environment and Versions (please complete the following information):
Using version 1.40 of this client.
