dual stack, expose, tests: port VM service tests

Port tests creating a VM entity, then starting it to instantiate
a VMI out of it.

Service entities will be created on the VM entity, and
connectivity to the service is being checked in the following
scenarios:
  - service created before the VM is started
  - after VM is rebooted
  - service stops working once VM is deleted
