[VM-monitor] Redundant messages

[NShaforostov]

Describe the bug

Sometimes VM-monitor sends messages with the content that VMs are not registered in a cluster and suggestion to delete them in the Provider console. But when manually checked, it turns out that these VMs are working well in the Cloud Pipeline deployment (with all mandatory labels) and also look well in the Provider console.

To Reproduce

Steps to reproduce the behavior:

1. Check emails from VM-monitor
2. Find email with the subject "VMs are not registered in cluster"
3. Check the VM from the email in the Cloud Pipeline deployment
4. Check the VM from the email in the Cloud Provider console

Expected behavior

VM is not registered in the Cloud Pipeline deployment or in the Cloud Provider console.

Actual behavior

VM is registered in the Cloud Pipeline deployment, has a correct label, job is running and available. VM is registered in the Cloud Provider console., has a correct label, VM is running and available.
