Disable metadata service detection in the emulator. (#6860)

* Disable metadata service detection in the emulator. Fix for #6765. The latest version of google-gax attempts to read from the metadata server (on an internal IP address). Setting the environment variable METADATA_SERVER_DETECTION=none by default will turn this behavior off. This is overridable with .env.local. * changelog
