Don't expose credentials

Don't expose credentials to tempest.conf when
--create-test-accounts is used.

When generating tempest.conf with demo creds, use
--create-accounts-file argument so that the argument
is tested in the gates.
The argument is used only on Devstack.

Tempest concurrency of devstack demo job is reduced to 1
because the minimal accounts file is used.
