Steps to reproduce:
1) Setup master node
2) SSH to the master node
3) Create file nginx.yaml with role description:
meta:
description: Install Nginx
name: Nginx
name: nginx
volumes_roles_mapping:
- allocate_size: min
id: os
4) Create new role from file with a command:
fuel role --rel 2 --create --file nginx.yaml
5) Go to the Fuel UI and create new environment.
6) Add controller, compute, and new nginx role to the environment.
7) Provide correct configuration for network, settings, etc.
8) Deploy environment.
Expected behaviour:
Deploy will fail, because there is no tasks for new role
Actual behaviour:
Deploy stucks. There is an error in the log:

I think this is because we "lost" error handling when added background tasks with mules.
We need to check if that is true
