Issue:
[v2] Remove special handling for pre-3.0 credentials
The Credential resource has a bunch of special behavior to accommodate old version switches.

I think this is because `user` and `team` used to be genuine fields, but these columns were removed in Tower 3.0. None of this is needed for post-3.2 tower-cli

Pull request description:
remove old version logic not needed in v2 API
Resolves #358

Some basic demoing:

```
$ tower-cli credential create --credential-type="Source Control" --inputs='{"username": "asdf", "password": "fdsa"}' --user=admin --name='asdf' -v
*** DETAILS: The credential_type field is given as a name; looking it up. *****
*** DETAILS: Getting the record. **********************************************
GET http://localhost:8013/api/v2/credential_types/
Params: {'name': 'Source Control'}

*** DETAILS: The user field is given as a name; looking it up. ****************
*** DETAILS: Getting the record. **********************************************
GET http://localhost:8013/api/v2/users/
Params: {'username': 'admin'}

*** DETAILS: Checking for an existing record. *********************************
GET http://localhost:8013/api/v2/credentials/
Params: {'name': u'asdf'}

*** DETAILS: Writing the record. **********************************************
POST http://localhost:8013/api/v2/credentials/
Data: {'inputs': {'username': 'asdf', 'password': 'fdsa'}, 'credential_type': 2, 'user': 1, 'name': u'asdf'}

Resource changed.
== ==== =============== 
id name credential_type 
== ==== =============== 
 8 asdf               2
== ==== =============== 
```

We might have some other bugs to file - it's not using credential type in the lookup, not providing name doesn't raise an error right away.
