API extension for accessing instance_actions
API extension for accessing instance_actions

Adds a new API extension for accessing the recorded actions and events
on an instance.  Usage is documented with api samples.

Additionally it modified the db api to retrieve actions by request_id
since the api does not return the db id.  This extension is the first
consumer of that method so there's no issue of changing behaviour
elsewhere.
