Add model Options.label property

[Tim Graham]

There are many places in Django that construct a dotted path like this:
'%s.%s' % (model._meta.app_label, model._meta.object_name)

It would by DRYer to add a property to the Options class in django/db/models/options.py that returned the dotted path. I'm proposing the name "label".

Yes please!

We also want to add a label_lower property that returns '%s.%s' % (model._meta.app_label, model._meta.model_name) as that's another repeated pattern.

What's the advantage of doing options.label_lower rather than options.label.lower()?

Or are these two different things?

[Markus Holtermann]

options.app_label is never converted to lower case.

[Baptiste Mispelon]

Ah yes, that makes sense. Sorry for the noise :)

About the documentation for this PR: I think we should make options.label and options.label_lower public API.

[Luis Del Giudice]

I've added tests, changes in the docs, looked for places in django source code old labels were used and replaced with model._meta.label or model._meta.label_lower
