Use --non-admin for non admin users in zuul jobs

python-tempestconf-tempest-packstack/devstack-demo zuul job
uses generate-tempestconf-file role to generate tempest.conf.
Since demo is a non-admin user with non-admin user we cannot use
--create option but it was used since it is a bug, so we need to
check for admin/demo user then enable the proper option.

Used Jinja templates for creating tempest configuration script

Create test-demo-user role which prepares resources for a demo
user.
Create generate-accounts-file role, which generates accounts.yaml
file for Tempest needed for running tests as user who doesn't
have persmissions to create resources.
