[ConfirmDialog] Add third, Cancel button

[x] feature request

Minimal reproduction of the problem with instructions

Currently ConfirmDialog only supports two buttons: Accept and Reject.

In several cases a third, Cancel button could be useful.

Take a look at options provided by WinAPI MessageBox function:

MB_ABORTRETRYIGNORE
MB_CANCELTRYCONTINUE
...
MB_YESNOCANCEL

It is impossible to implement scenarios covered by these options using PrimeNG's ConfirmDialog, because it is limited to two buttons.

To illustrate, if I need to ask the user about unsaved changes when they are about to leave the page, I would like to display some sort of a MB_YESNOCANCEL dialog:

Unsaved changes
----------------------------

Do you want to save changes?

         [Yes] [No] [Cancel]

I have prepared a draft implementation: https://stackblitz.com/edit/primeng-confirmdialog3

Please tell us about your environment:

• Angular version: 7.2.8
• PrimeNG version: 7.1.0
• Browser: all
• Language: TypeScript 3.3

I second this request!

I third this request, but for the Confirm Popup as well. We use the Confirm Popup a lot in our UI and have a situation where we need two confirm buttons and one cancel button - 'Save', 'Save New Revision', and 'Cancel'. I'm surprised this hasn't gotten asked for more often. The Confirm popup is already super useful, but it would be even better if it were a bit more flexible with the number of buttons it can display.
