Fixes #37433 - Set indentation when calling subscription_manager_setup

Adding proper indentation when calling snippet subscription_manager_setup

[ekohl]

I'd argue the rest of the subman code should be not indented since at the bash level they're not conditional. The Ruby conditionals shouldn't matter for the end result.

The problem I'm trying to solve is the final rendered result of cloud_init_default.erb.

subscription_manager_setup.erb is fine.

redhat_register.erb is also fine and generates valid bash script.

However, when rendered, redhat_register.erb result does not have the same indentation. Code that comes from redhat_register.rb have 2 space indentation, but what is generated by the snippet has no indentation at all. That's fine if that result is simply being processed by bash.

The problem is that cloud_init_default.erb (which consumes redhat_register.erb) is supposed to generate a valid yaml as result. With that difference on indentation coming from redhat_register.erb its result is not a valid yaml.

I wouldn't mind if we removed all the indentation from redhat_register.erb. That would do the trick too. What matters is that the rendered result should have the same indentation.

@ekohl , this is how the template looks like when it's rendered without the indentation:

If we indent the internal snippet, it will pass the validation:
