Move type LabelSelector and type LabelSelectorRequirement from pkg/apis/extensions This avoids an import loop when Job (and later DaemonSet, Deployment, ReplicaSet) are moved out of extensions to new api groups. Also Move LabelSelectorAsSelector utility from pkg/apis/extensions/ to pkg/api/unversioned/ Also its test. Also LabelSelectorOp* constants. Also the pkg/apis/extensions/validation functions ValidateLabelSelectorRequirement and ValidateLabelSelector move to pkg/api/unversioned The related type in pkg/apis/extensions/v1beta1/ is staying there. I might move it in another PR if neccessary.
