when using ubuntu, dont remove apparmor

playbooks/roles/openldap/tasks/debian.yml  in the file, there is remove apparmor, but ubuntu os depends on snap, snap depends on apparmor, so i think we should remove this code
- name: Remove Apparmor package
  vars: 
    package_name: 
      - apparmor
    package_state: absent
    package_purge: true
  include_role: 
    name: safe_yum
