Record management - Add events in the audit trail

Description

the goal is to add the missing events in the Nuxeo Audit Trail:

• Log an event when the retention period starts:
  • right after the application rule is applied for immediate retention
  • when the event occurs for an event based retention
• Log an event when the retention expires
• The event "Retention period updated" is displayed, including the new expiration date in the comment, on the history of the document / Audit when I override the retention period
• The event "Applied Legal Hold" is displayed on the history of the document / Audit when I apply a legal hold to a document,
• The event "Removed Legal Hold" is displayed on the history of the document / Audit when I remove a legal hold from a document,
