This commit implements policy in code for (static) actions
API. The default rules for the (static) actions API were
removed from the policy.json and moved into code under
`murano.common.policies.action`.
This commit specifically:
- Moves policy actions related to the (static) actions
API from the policy.json into code.
- Documents the API information and paths associated with
each actions-related policy.
Partially Implements: blueprint policy-in-code
