This bug was initially created as a copy of Bug #1968382

I am copying this bug because: 



+++ Description of problem:

When creating a BMH resource without `inspect.metal3.io` annotation, the value is not being automatically set.


+++ Steps to Reproduce:

1. Create BMH without `inspect.metal3.io: disabled`

+++ Actual results:

```
# oc -n assisted-installer-bughunter-1 describe baremetalhost.metal3.io/ostest-worker-0

[...]

Name: ostest-worker-0
Namespace: assisted-installer-bughunter-1
Labels: infraenvs.agent-install.openshift.io=myinfraenv-bughunter-1
Annotations: <none>
API Version: metal3.io/v1alpha1
Kind: BareMetalHost

[...]

Provisioning:
ID: 0fada510-dd4d-40b8-ada6-07aad06d41c8
Boot Mode: UEFI
Image:
URL:
State: inspecting

[...]

Events:
Type Reason Age From Message
---- ------ ---- ---- -------

[...]
```

In the UI machine goes into "inspecting" state. In the serial console it can be seen that the IPA is booted.

+++ Expected results:

```

```

Machine should go directly into "provisioned" state.
