Adding more visible hints.

[Rancho-7]

When we try to add a new monitor for OS,should we set Password or PrivateKey as required,like Username?

I think this will give the user more friendly hints,because if these two parameters are both not filled in,it will prompt a authentication error.

I am not sure if it is really needed,so I would like to discuss about it here with everyone.

Hi, due the either password or PrivateKey is required, it is difficult to determine the display here.
