Traffic Types not handled correctly

I tried to import traffic types into terraform, but they all got imported as "Management".

The problem is that it looks for 'name', which doesn't exist, so it always defaults to Management. The API returns 'traffictype'.

This appears to be an issue also /w the upstream cloudstack go library, and even the freaking API documentation. 🤪

Here is what I get when I do the request via cloudmonkey, and I confirmed I got the same results from CloudStack python package.
```
