Streamline simulator image to latest cloudstack release

[resmo]

the integration tests run on an simulator image with cloudstack 4.11.

Container image repo https://github.com/ansible/cloudstack-test-container

Which version should that be? 4.13 LTS or 4.14?

[resmo]

I prefer LTS because this is what most users use in production.
