message.error/success/... duration argument is optional

[monkindey]

What problem does this feature solve?

Because duration have the default value.

message.error(content, duration, onClose)

Sometime I want to use onClose, but have to reassign value to duration even equal to the default value.

What does the proposed API look like?

I can use it two way.

message.error(content, duration, onClose)
message.error(content, onClose)

duration is optional, we can identify the onClose using the typeof

Hi, @benjycui . Do you use prettier to format ts code in antd project ?
