Update source reference when templating terraform modules

Background

cloud-platform cli has commands to create ecr, rds, s3 and serviceaccount terraform module. The template to generate the files are places under the module /examples folder. And these /examples folder is also used for unit tests so they refer to the relative path

Proposed user journey

This means when user run the commands with the cli, the code generated doesnt contain latest release or has some relative source path

Approach

Update the cli to fetch the example and update the source reference from the module and the latest release
