Documentation explaning on "Admin" and "Restricted Admin"

At the current moment, the description in the Bamboo and the documentation is very brief on the "Restricted Admin" permissions. To Quote:

Restricted Admin - User can perform some administration operations and view all plans in Bamboo.

However, there is no official documentation on what this permission allow the users to perform. The current documentation is at https://confluence.atlassian.com/display/BAMBOO/Bamboo+permissions

Suggestion:

1. List down the operations that can be perform by users with the "restricted admin" permission.
2. At least update it to a more clear description like the one from pbruski at this answer:

   A restricted admin is an admin that doesn't have some of the permissions that directly influence the host on which the Bamboo Server is located. All plan administration and agent administration is available to restricted admins.
