Support for Google Cloud Deployment Manager Templates

Based on going through documentation, Serverless support for Cloud Functions, seems to be very minimal, which make its usage highly inflexible.

With AWS, even if such a problem does exist, we could get around it, using the Cloud Formation Template in the serverless.

However, no such support seems to exists for Google Cloud Deployment Manager template.

Please let me know if this support exists today(using any additional plugins or by default) and if so, reference to any documentation that describes use of the same. If it does not exists, please let me know if you have any plans to support the same in recent future and any timelines for the same.
