Introduce cloud-speech API config yaml. (#66)

* Introduce cloud-speech API config yaml.

- changed RecognizeNonStreaming() to idempotent

"Recognize" method is a bidi-streaming method, which is not
supported by Gapic codegen, but yet it should exist when
we want to support it for some language.

Anyways streaming methods will be ignored as
https://github.com/googleapis/toolkit/pull/328

* Fix Java namespace

* Fixes

- timeout to 60 seconds
- modified nodejs config (for integrating with gcloud-node project)
