Lack of support for domain based Redfish URL and TLS certificates

[mastier]

The customers would like to use domain names and globally valid certificate.
However hardware-observer currently rely on bmc address fetch by ipmitool

It would be good to add support for redfish-hostname as optional argument

hardware-observer-operator/src/hardware.py

Line 67 in e51d69b

def get_bmc_address() -> t.Optional[str]:

hardware-observer-operator/src/hw_tools.py

Line 546 in e51d69b

health_check_endpoint = f"https://{bmc_address}:443/redfish/v1/"

Optionally support for adding RootCA certificate that will verify the certificate against.
Currently the cert verification is skipped.
