ModelAdmin should allow not default manager

[Alon Levy]

My use case is this:

I have a model with two Managers - one named objects (the default), and another one. I want the admin to use the non-default one (in my case I can't even give it the default one since it doesn't return instances of the model, but of another model it inherits from). So my solution (It doesn't even merit a patch - its just 3 lines changed in django/contrib/admin/options.py):

# my code
from django.contrib import admin

class MyAdmin(admin.ModelAdmin):

model = MyModel
manager = MyModel.othermanager

This is pretty much a duplicate of #7510 (which has a required additional patch and more info).
