CRDs for AF or Region mappings are scoped to namespaces. So an
admitted pod has to be mutated with CRDs existing in the same
namespace as the pod's.
Closes#167
Currently we have hardcoded mapping from human readable names of
AFs and FPGA regions like arria10-nlb0 to the resource names
produced by the FPGA device plugin. This is not sustainable
long term solution.
Implement CRD based mappings so that a new mapping can be added or
removed dynamically by cluster admins with CRD resources.
