Request to update Google Stackdriver integration to accept requests from webhooks v1.2

Issue Summary

According to Google's official documentation, Stackdriver alert notification webhook has a 1.2 version that adds a lot more payload data as compared to 1.1. Upon reading official documentation for OpsGenie's Stackdriver integration, only version 1.1 is available for use. Any plans to implement 1.2? I am looking forward to utilizing documentation in my OpsGenie notifications.

Workaround

Use existing integration with webhooks v1.1
