Omit id for objects during export with filtree_create

[przemkalit]

What does this PR do?

Propose a solution that allows exporting objects without IDs.

Background: In our environment, the inclusion of IDs in the filenames is causing a slight mess in our GitHub repositories. Imagine the following situation:

1. I exported a project with job templates from the DEV environment.
2. I imported it into the TEST environment.
3. I created a new job template in the TEST environment for this project.
4. I exported the project with job templates again, but this time from the TEST environment.
5. I discovered in the repository that there are files of job templates with both DEV and TEST IDs.

How should this be tested?

- name: Get objects
  hosts: all 
  roles:
    - role: infra.controller_configuration.filetree_create
      vars:
        omit_id: true

LGTM.

Could you add an extra space just after else '' to look consistent with other variables, resulting like else '' }}?

Another point is to add the new input variable in https://github.com/redhat-cop/controller_configuration/blob/devel/roles/filetree_create/README.md and in https://github.com/redhat-cop/controller_configuration/blob/devel/roles/filetree_create/meta/argument_specs.yml

Ok, I've added the spaces, spotted missing id for teams and updated the documentation.
