Obsolete API Key support for Google Authentication (API Key) node

This node desperately needs to be updated to support JSON key formats. P12 keys have been deprecated by Google, and use of JSON keys is highly recommended:

Recommendation: We recommend that you use JSON (.json) private keys to activate service accounts. JSON private keys do not require the special crypto library explained on this page. To create a new JSON private key for a service account, follow the steps in Authorizing with a service account. For steps to activate the service account with the Google Cloud CLI, see gcloud auth activate-service-account. The rest of this page isn’t applicable if you use JSON private keys.

What are the plans to update this node to support current API key standards and recommendations?
