Redfish in bmc-config commissioning script is hard-coded for a particular Manager and EthernetInterface

[Paul Jonason]

Code within Redfish class's _get_bmc_ip in the bmc_config commissioning script looks to a specific url:
url = f"https://{self._redfish_ip}:{self._redfish_port}/redfish/v1/Managers/1/EthernetInterfaces/NIC"

But Manager IDs vary among bmc providers, as do the Manager EthernetInterfaces.

Can't remember how to tie these together, but I do have code to propose to fix this in https://code.launchpad.net/~pjonason/maas/+git/maas/+ref/redfish-bmc-config-2054836

[Paul Jonason (pjonason)]

The proposed code finds the ID of the local Redfish Manager, then finds the collection of Manager EthernetInterfaces, and returns the IP address of the likely active Manager interface (that is, it will reject interfaces having an IP address of 0.0.0.0, 16.1.15.1, or anything starting with 169.254).

The ID of the local Manager was broken out into its own method so it can populate the node_id field in the Redfish power driver.

Also, I found a few bmcs return 201 on Session creation, so I included that in an array of acceptable return codes.
