Do not use system scope tokens in providers

This is partial revert of 5ca6e6fc9cb2403307114877ece24e394be35794 .

After discussing several problems caused by scope separation, we
decided to suspend implementing the scope enforcement and focus on
project personas like reader role. As the result of that decision,
the system admin persona will be removed, thus we should use
the project admin persona instead. The previous policy rules to allow
system scope access have been reverted by [1].
