"Set local httpd user passwords" task fails on Debian Stretch

[ganto]

Role is affected by upstream issue ansible/ansible#20199. This means if the Ansible host is running Ansible < 2.3.2 or < 2.4.0 and the Check_MK server is running Debian Stretch with python-passlib-1.7.0-2 the playbook run will abort with the following error:

TASK [debops-contrib.checkmk_server : Set local httpd user passwords] ***************************************************************************************************

Work-Around:
Until a fixed Ansible version is released, apply patch ansible/ansible#20202 manually to your currently used Ansible installation.
