* trigger validation as soon as a Subscription Request is submitted
* decrease slapos_subscription_request_validate_submitted alarm periodicity
* create Subscription Request as soon as a Compute Node is validated
* create Subscription Request as soon as Instance Tree is validated

* test Compute Node subscription creation
* logout test

Let's automate everything for now

slapos_cloud: only propagate Instance Tree parameters to the Software/Slave Instance only if an Open Sale Order exists
