Description Lital Alon 2021-06-23 19:21:20 UTC 
Description of problem:
host_requirements API: 
https://api.stage.openshift.com/api/assisted-install/v1/host_requirements

Resulting:
{
    "master": {
        "cpu_cores": 4,
        "disk_size_gb": 20,
        "installation_disk_speed_threshold_ms": 10,
        "ram_gib": 16
    },
    "worker": {
        "cpu_cores": 2,
        "disk_size_gb": 20,
        "installation_disk_speed_threshold_ms": 10,
        "ram_gib": 8
    }
}

The issue is that it doesn't contain network_latency_threshold_ms and packet_loss_percentage.
This can be helpful for automation purposes (use threshold from API, per role, rather then using hard coded values)

Note that those values can be taken from .../clusters/5ad7bbd4-be9e-4bc3-96c6-6a6e505c00ec/host-requirements
this return per host HW info, but it require to parse each host and compare its id
