commit 522af14a098a05862e61f19228a7b291fcd7cba6

[C++] Handle OAuth 2.0 exceptional cases gracefully (#12335)
Fixes #12324
Currently if any error happened during OAuth 2.0 authentication in C++
client, a runtime error would be thrown and could only be caught when creating
an `AuthOauth` object, but could not be caught in `Client`'s method like
`createProducer`. It's not graceful. What's worse, there's no way for Python
client that is a wrapper of C++ client to caught this exception.
When `ClientCredentialFlow::authenticate` returns an invalid
`Oauth2TokenResult`, catch the `runtime_error` thrown in `Oauth2CachedToken`'s
constructor and returns `ResultAuthenticationError` as
`AuthOauth2::getAuthData`'s returned value. Since `getAuthData` always returns
`ResultOk` before this PR, the related docs are also modified.
Then when a CONNECT or AUTH_RESPONSE command is created, expose the result
of `getAuthData`. If it's not `ResultOk`, close the connection and complete the
connection's future with the result. After that, the `Client`'s API will be
completed with the result.
In addition, this PR also makes the error code of libcurl human readable by
configuring `CURLOPT_ERRORBUFFER`.
- [x] Make sure that the change passes the CI checks.
This change added tests `AuthPluginTest.testOauth2Failure` to verify when
OAuth 2.0 authentication failed, the `createProducer` would return
`ResultAuthenticationError` without any exception thrown.
