Validate GUID was provided when ib-kubernetes is enabled

[adrianchiris]

When ib-kubernetes integration is enabled, it is expected that GUID is provided in network configurations in either:

1. "guid" CNI Arg
2. "infinibandGUID" Runtime config

Fail in the unlikely case where none of the above is present.
