Label selector != works in get exporter but not to create lease

[ewchong]

Works:

jmp get exporters -l revision!=v3,board-type=qc8775
NAME                                    LABELS                                                                                           
qti-snapdragon-ride4-sa8775p-03         board-type=qc8775,device=qti-snapdragon-ride4-sa8775p-03,enabled=true,location=bos2              
qti-snapdragon-ride4-sa8775p-10         board-type=qc8775,device=qti-snapdragon-ride4-sa8775p-10,enabled=true,location=bos2              
qti-snapdragon-ride4-sa8775p-22         board-type=qc8775,device=qti-snapdragon-ride4-sa8775p-22,enabled=false,location=bos2

Doesn't work:

jmp create lease -l board-type=qc8775,revision!=v3 --duration 1d  -o json
Error: grpc controller responded: "!=" is not a valid label selector operator

So I investigated a little bit, and for the API cals we are using labels.Selector (API interface for runtime calls) for get exporters, from k8s./io/apimachinery/pkg/labels,

but when we create a lease we convert to metav1.LabelSelector, that has a different parser and does not parse !=.

We can parse with labels.Selector, and then convert to LabelSelector (the CRD storage of the lease)
