bug#71290: Options for viewing project buffers

[mikpom]

Greetings devs and emacs community.

I occasionally need to list buffers of a project and do so with the
built-in command project-list-buffers from project.el. The problem is
that this command utilizes Buffer-menu mode and does so in a hard-coded
way. Personally I prefer IBuffer which is already heavily customized
while I have zero knowledge of Buffer-menu mode. 

I suggest to make an option whether project.el will list buffers with
Ibuffer, Buffer-menu or even something else?

Kind regards,
-Mikhail
