The only purpose of the module `test_documentation_examples` is to test
a few of the code examples shown in the developer documentation.

As de86b3fb79e removes the documentation sources from the repository,
the test module is removed as well.

Purpose
=======

The current kanban view is messy. It is difficult to identify which
apps are installed or not. The user can completely miss a module
that might have interested him. A search panel would make things way
more readable.

assertDictContainsSubset has been deprecated since 3.2 and is not
documented anymore, apparently because the order of its parameters is
less than obvious.

Consequently, remove the call to said dict & replace it with
assertions on item sets.

Note: the odd formatting is because these bits are literal-include-ed
in the documentation as sub-slices (just the relevant code lines), so
ideally they shouldn't be moved around and no additional content
should be added to those specific lines.

update Model Inheritance Delegation docs with a more meaningful example

Purpose of this commit is to give description more "business oriented"
because those descriptions appears in Odoo Studio which is supposed to be used by end users, not only by developers.

The test is surprisingly formated but it is to be able to extract the relevant
lines in the documentation
