role + local actions (cloud deployment)

[ProfHase]

I want to automate the complete deployment in cloud with ansible. The Role should create a host in cloud before the deployment starts.
The Problem is: One cannot use `local_action` in roles. How do you manage it?

I 'd like to use something like

#myrole/tasks/prepare.yml

- local_action:
 module: cs_instance
 name: {{ instance_name }}
 iso: Linux Debian 7 64-bit
 hypervisor: VMware
 project: Integration
 zone: {{ instance_zone }}
 service_offering: 1cpu_1gb
 disk_offering: {{ disk_offer }}
 disk_size: 20
 networks:
 - Server Integration
 - Sync Integration
 - Storage Integration

#myrole/tasks/main.yml

- include: prepare.yml

- name: create users
  user:
  ......

And define all the variables in `host_vars` (already before the host is created). Is there any way to do this?
