hello，
When I dev on windows platform，

    obj = {
        "apiVersion": "v1",
        "kind"      : "ReplicationController",
        "metadata"  : {
            "name"     : "frontendcontroller",
            "namespace": "bravelib"
        }
    }
    api = init_clound_api()
    pykube.ReplicationController(api=api, obj=obj).delete()

She can not work， I found

Line:70
When I add The following lines code ，She can Delete it，

import platform
if 'Windows' in platform.system():
    kw["url"] = kw["url"].replace("\\", "/")
