Description of problem:

running metrics deployment  requires encrypting the /etc/ovirt-engine-metrics/secure_vars.yaml.example file.

this produce 2 issue:

    "message": "an error occurred while trying to read the file '/etc/ovirt-engine-metrics/secure_vars.yaml': [Errno 13] Permission denied: '/etc/ovirt-engine-metrics/secure_vars.yaml'"
}
