Story

As a devops engineer,
I would like to use a module to configure an externally-created space,
So that I can benefit from setting users and ASGs while using the default created spaces

Solution

### Tasks
- [ ] Split space users and space asg code into a space_config module
- [ ] use space_config within `cg_space`
