I'm creating this issue to encapsulate all the documentation issues and tasks that we consider required before reaching GA.

Target: 7.10

• RBAC changes introduced in 7.10 (Existing docs are no longer accurate)
• There's no mention of the Stack Alerts feature: we still use the term built-in for Index Threshold and there's no mention of Geo Threshold
