Grant privileges and roles needed to read Auditbeat data from Kibana

Kibana users typically need to view dashboards and visualizations that contain Auditbeat data. These users might also need to create and edit dashboards and visualizations.

To grant users the required privileges:

1. Create a reader role, called something like auditbeat_reader, that has the following privilege:

   Type	Privilege	Purpose
   Index	read on auditbeat-* indices	Read data indexed by Auditbeat
   Spaces	Read or All on Dashboards, Visualize, and Discover	Allow the user to view, edit, and create dashboards, as well as browse data.

2. Assign the reader role, along with the following built-in roles, to users who need to read Auditbeat data:

   Role	Purpose
   monitoring_user	Allow users to monitor the health of Auditbeat itself. Only assign this role to users who manage Auditbeat.
