This patch removes a couple of tempest.conf settings that are being
overwrriten when Keystone is set to enforce scope.
These settings are already being set by the keystone devstack plugin [1]
and do not need to be overwritten here.
Keystone is changing the default admin credentials to be project-admin
instead of system-admin to address some failing tests in services that
require project-scoped admin for their admin APIs. [2] These overrides
are preventing that change from taking effect.
