Description of problem:
When there was no ssh connection, and host is not saved in .ssh/known_hosts ansible playbook becomes interactive and need yes to add ECDSA key fingerprint. Not sure how I got to the state that host wasn't in the .ssh/known_hosts, but it was quite fresh engine upgraded from older 4.1.0 version.

For reproducer you just need to remove the host from it.


Version-Release number of selected component (if applicable):
ovirt-engine-metrics-1.0.1-1.el7ev.noarch

How reproducible:
100%

Steps to Reproduce:
1. remove Host from .ssh/known_hosts
2. run /usr/share/ovirt-engine-metrics/setup/ansible/configure_ovirt_hosts_for_metrics.sh 

Actual results:
Ansible playbook waits for yest input on adding host to known

Expected results:
Should add unrecognized hosts automatically

Additional info:
[root ~]# /usr/share/ovirt-engine-metrics/setup/ansible/configure_ovirt_hosts_for_metrics.sh
