Rename nzTitle based on the directive

What problem does this feature solve?

Having nz-tooltip, nz-popconfirm and nz-popover on the same component makes some behaviors impossible because both of them use the same input for the title: nzTitle.

This means that if you want to create a button that has a tooltip and a popover on click, you won’t be able to show a tooltip at all.

What does the proposed API look like?

Use nzPopoverTitle, nzPopConfirmTitle and nzTooltipTitle as optional second input, with an implicit setter in order to map these to the effective input value and minimize the impact of this change while providing a way to solve this issue.

I’m not sure these are the only directives that should be modified, but they are the ones I spotted so far.

This behaviour can already by achieved. I think renaming directives is a breaking change and should not be done especially when it is already working. Check this StackBlitz for a working example

<span nz-popover nzTitle="Popover" nzContent="Content">
    <span nz-tooltip nzTitle="This is a button" >
       <button nz-button nz-popconfirm nzTitle="Are you sure to press this button?" >
          Button
       </button>
    </span>
</span>
