This commit implements policy in code for the environment templates
API. The default rules for the environment templates API were
removed from the policy.json and moved into code under
murano.common.policies.env_template.
This commit specifically:
- Moves policy actions related to the environment templates
API from the policy.json into code.
- Documents the API information and paths associated with
each environment template policy.
- Updates the ``create_environment`` policy action documentation
in murano.common.policies.environment to include API
/v1/templates/{env_template_id}/create-environment
which enforces this policy as well.
Partially Implements: blueprint policy-in-code
