api_curl_examples.rst is out of date

[Dave Chen]

Two example in the `api_curl_examples.rst` is not accurate anymore, we need to update the docs.

1. Default scope - Get an token with default scope (may be unscoped)
Since this example is trying to get an unscoped token, so there will be no catalog associated with the token, so the response is not correct.

2. Getting a token from a token
The example here is also trying to get a unscoped token from a existing token, so there will no catalog associated with the token, so the response is not correct.

"Default scope" refers to a user's default project ID - which may result in a scoped token with a catalog.
