Commit Message

Add PreallocatedMode skeleton for predetermined GUID lookup

In pre-allocated mode the GUID for a pod's IB network is a deterministic
function of (pkey, hca index, node index) rather than a free GUID pulled
from the pool. This is for substrates where we are not the UFM fabric
admin and GUIDs/PKeys are pre-provisioned by the provider (IREN B300s).

- Add PREALLOCATED_MODE config flag (DaemonConfig), default false so
  existing substrates are unchanged.
- Branch in processNetworkGUID: use LookupPredeterminedGUID when the flag
  is set, else GenerateGUID (unchanged).
- LookupPredeterminedGUID extracts pkey (CNI spec), hca index (networkID
  trailing number) and node index (node name suffix). The deterministic
  encoding itself is stubbed (TCL-7011) and returns not-implemented.
- Unit tests for the hca/node index parsers.
