WHY IT NEEDS A POLICY

Why create_template_from_vm needs a policy

This tool creates a new template artifact from a virtual machine, which is a reversible write operation that creates data/resources in CloudStack infrastructure.

From the tool's definition Tool name 'create_template_from_vm' and description 'Create template from virtual machine' indicate a creation operation that modifies infrastructure state by generating a new template resource from an existing VM.
