Toast: Queue Priority?

[enjidev]

I was just reading this and thought a queue-priority feature for Toast would be useful.

We already have a type prop that might be used, but adding a priority option would give users explicit control.

That's a good idea. What possible values do you imagine for this priority property?

An alternative is to open it up to the user to decide the queue priority and keep priority as string

Take a look at #2628 and let me know your thoughts
