Execution History and Replay

As a developer, the result of a web trigger execution is stored in the repository. Enough information are stored that lets me replay the trigger if needed.

Impl: We decided to store the result as a DocumentModel under the following hierarchy: /StudioProjects/XXX/WebHooks/YYY (with XXX as project symbolic name and YYY GUID of the history log). The WebHooks folder is created lazily.
=> The worker of NXS-6641 should take this DocModel as param and set the status/message/timestamp on it
 
Said differently, we serialize the http request in this doc model

AC:

• I have a service that can execute a NXQL request to select all the hook executions logs from a hook configuration.
• The execution record stores HTTP Status, HTTP Messages, timestamps
• I have a way to schedule a new execution based on a result log.
