Pin kubernetes below v36 to avoid breaking API changes

kubernetes v36 introduced two regressions that break local and staging operation:
1. ApiClient.__deserialize_model() now accesses self.configuration which is unset
   when constructed via ApiClient.__new__() (bypassing __init__).
2. _set_config() stores exec credentials under api_key['authorization'] but
   auth_settings() was changed to check api_key['BearerToken'], leaving all
   requests unauthenticated (system:anonymous).
