after power off

Description of problem:
When checking the metal3 metrics on the fresh cluster, these metrics don't appear in the log:
metal3_host_error_total
metal3_operation_power_change_total
metal3_host_config_data_error_total
metal3_operation_deprovision_duration_seconds

When powering off and back on one of the workers observed the first appearance of the metrics. Logs before and after are attached

Version-Release number of selected component (if applicable):
Openshift: 4.4.0-0.nightly-2020-04-01-005209

How reproducible:
100%

Steps to Reproduce:
1. Deploy a cluster, observe metal3 metrics in cli: curl http://localhost:8085/metrics
2. There is a number of meal3 metrics, found in metal3 pod, metal3-baremetal-operator:
metal3_reconcile_error_total
metal3_credentials_missing_total
metal3_credentials_invalid_total
​​metal3_credentials_unhandled_error_total​​
​​metal3_credentials_updated_total​
metal3_credentials_no_management_access_total
​​metal3_operation_register_duration_seconds
​​metal3_operation_inspect_duration_seconds
​​metal3_operation_provision_duration_seconds
​​metal3_provisioning_state_change_total
​​metal3_host_registration_required_total
​​metal3_delete_without_deprovisioning_total

2. According to the source code, these are also supposed to appear:
​​metal3_host_error_total
metal3_operation_power_change_total
metal3_host_config_data_error_total
metal3_operation_deprovision_duration_seconds

3. In UI turn off and back on one of the workers. Then deprovision it. 

Actual results:
The metrics of metal3_operation_power_change_total and metal3_operation_deprovision_duration_seconds appear

Expected results:
The metrics appear from the beginning
