Description:
With the arrival of SET PERSIST/PERSIST_ONLY the session user should allow the use of such tools in the advent of auto configuration features in the server/plugins.

As of now, attempts to do so will result in 
Access denied; you need SYSTEM_VARIABLES_ADMIN and PERSIST_RO_VARIABLES_ADMIN privileges for this operation
 

How to repeat:
Try to use SET PERSIST on sql_command_test.cc 

Suggested fix:
Add SYSTEM_VARIABLES_ADMIN and PERSIST_RO_VARIABLES_ADMIN privileges to the  mysql.session_user.
