Support aks of kuberflow training service
Support nnictl set nniManagerIp

Add nniManager Ip in nnictl, pai TrainingService and kubeflow TrainingService.
If users set nniManagerIp, pai and kubeflow will use this ip instead of using getIPV4() function.
Web UI will also use this nniManagerIp.

In nnictl, classArgs is not required, now set it as optional for some kind of tuner and assessor may not require classArgs.
