openshift-ansible: Install fails with "the output has been hidden due to the fact that 'no_log: true' was specified for this result"

Description

When I try to install a single-node biy version I get the following error

TASK [openshift_metrics : slurp] ***********************************************
ok: [master.some_domiain.ch -> localhost]

TASK [openshift_metrics : generate htpasswd file for hawkular metrics] *********
fatal: [master.some_domiain.ch -> localhost]: FAILED! => {"censored": "the output has been hidden due to the fact that 'no_log: true' was specified for this result"}

Version

ansible 2.2.2.0 (also tried with 2.3.0.0-3.el7)
openshift-ansible-3.5.67-1-4-g5b874ad

Steps To Reproduce

1. run ansible-playbook openshift-ansible/playbooks/byo/config.yml --inventory hosts

Expected Results

OpenShift to be installed correctly including metrics

ansible-playbook openshift-ansible/playbooks/byo/config.yml --inventory hosts
TASK [openshift_metrics : slurp] ***********************************************
ok: [master.some_domiain.ch -> localhost]

TASK [openshift_metrics : generate htpasswd file for hawkular metrics] *********
fatal: [master.some_domain.ch -> localhost]: FAILED! => {"censored": "the output has been hidden due to the fact that 'no_log: true' was specified for this result"}

Additional Information

This is the inventory file I used
