Check client version iif not given

[jacopofar]

The docstring states the api_version and api_version_auto_timeout_ms are used to decide if check_version() has to be called and for how long it has to wait, now the function follows that behavior, consistent with the KafkaClient

This could help with problems like #1308

I found later that this behavior was introduced in #1953 because if check_version() is not called calls to get_api_versions() will fail.

Could it make sense then to remove the api_version parameter which is not used and pass the api_version_auto_timeout_ms timeout to it?

Possibly related #2107 / #2108 ... as I noted #2108 (review), we should probably step-back and re-examine the way this gets handled so that it's consistent everywhere.
