New description:
The features of `sage.combinat.cartesian_product.CartesianProduct` are now
completely integrated into the category framework (see #18290). We remove
all occurrences of `CartesianProduct` to either `cartesian_product` or
`itertools.product`. We deprecate the `CartesianProduct` from
`sage.combinat.cartesian_product`.
In order to support all features of the old class we also:
- move the `__iter__` from
`EnumeratedSets.CartesianProducts.ParentMethods` category to `Sets`
- allows `cartesian_product` to be called with `list`, `tuple`, `set`,
`frozenset`
- introduce a function `bounded_number_of_tuples` in `sage.misc.misc`
that is intensively used in the testing framework
- refine the category of `Set([1,2,3])` to be finite
- implement a (very naive) `random_element` for `Set([1,2,3])`
- implement a (naive) hash for `EnumeratedSetFromIterator`
