missing support for new feature "get_ignored" group in ansible

"ansible-gitlabsos-playbook" seems to be missing one of the lastest features of get to exclude hosts from the get playbook runs.

to recap the history there was a problem where GET would run on the all group and would install gitlab on all hosts even if they were only for services around gitlab lets call them support services one example would be minio but others like monitoring are affected as well. to solve this problem support for the group get_ignored was introduced in the GET Installation Methode. this group is "simply" excluded from get.
