Fix DELL PowerEdge iDRAC

[damyan]

The DELL iDRAC needs some time before it can deliver source information. Asking "too soon" leads to HTTP 503:
stderr F 2024-11-08T09:24:55Z ERROR Reconciler error {"controller": "server", "controllerGroup": "metal.ironcore.dev", "controllerKind": "Server", "Server": {"name":"mgmt-1-system-0"}, "namespace": "", "name": "mgmt-1-system-0", "reconcileID": "6b4398aa-9256-4ce5-8e29-d23003ed8565", "error": "failed to update server status: failed to get system info for Server: failed to get systems: failed to retrieve some items: [{\"link\":\"/redfish/v1/Systems/System.Embedded.1\",\"error\":\"503: {\\\"error\\\":{\\\"@Message.ExtendedInfo\\\":[{\\\"Message\\\":\\\"iDRAC is currently unable to display any information because data sources are unavailable.\\\",\\\"MessageArgs\\\":[],\\\"[email protected]\\\":0,\\\"MessageId\\\":\\\"IDRAC.2.8.SYS518\\\",\\\"RelatedProperties\\\":[],\\\"[email protected]\\\":0,\\\"Resolution\\\":\\\"Wait for the data to be available and retry the operation.

A retry mechanism should be Implemented to work around the issue.

@defo89 @stefanhipfel have you seen this on Dell servers before, that the BIOS info after a reboot is not immediately available through Redfish?

No, I haven't seen this on the Dell servers we have (PowerEdge R660, iDRAC Firmware Version 7.10.30.05)

We tested it with a PowerEdge R440.

I added polling to wait for redfish system resources
