Add a view to UrlDispatcher for iterating over all registered routes.

[asvetlov]

Now the class has support for iterating over named routes only.
We should do the same for all routes (named+unnamed).

[asvetlov]

I'd like to have .named_routes() as well as .routes().
Any volunteer? The patch is very easy.

[jashandeep-sohi]

Should .named_routes() return a dict-like object or is a RoutesView sufficient?

[asvetlov]

It should return a read-only collections.abc.Mapping I guess.
Do you have another idea?

[jashandeep-sohi]

types.MappingProxyType already implements a read-only interface over a mapping. So I think this should be enough:

def named_routes(self):
    return types.MappingProxyType(self._routes)

[asvetlov]

Wow! You are right.
Would you provide a PR with test and docs?

[jashandeep-sohi]

Yes.

Fixed by #622
