As system, changes on Tests, Preconditions, Test Sets, Test Plans and Test Executions should be logged in the issue's activity/history

Xray must provide a way to see the activity/history for Xray issue types. Any change in Xray data must be logged in this view.

E.g.

• Editing Test Specifications
• Adding/removing links to other Xray entities: Adding Tests to Test Sets, Test Plans, etc

This must be implemented as a separate web panel right next to the Jira issue history called  "Xray History".
