Add a way to edit domain in Mastercontainer GUI.

[PasserDreamer]

In the README said:

How to easily log in to the AIO interface?
... Note: You can change the domain/ip-address/port of the button by simply stopping the containers, visiting the AIO interface from the correct and desired domain/ip-address/port ...

Expected:
A textbox that you can edit domain when all container stopped.

Result:
No way I can do on the management web page.

Hi, I guess you are looking for this? #362 (reply in thread)

Yes, but if GUI has it would be appreciated.

No, we will not add this for now but I will document how to do this in #933
