This patch implements the changes in the API required for the
skipped action blueprint. It includes:
- New field `status_message` is visible in API get calls for Audits,
ActionPlans and Audits.
- New Patch call is added to `/actions/{action_id}` which allows to
manually move actions in PENDING state to SKIPPED for ActionPlans
which have not been started.
- A new API microversion 1.5 is added for these changes.
It also adds requried tests and documentation.
