Feature: Check that specific object present in List

Motivation
It's a common use case to check if some object present in list. There are objects with overridden and not overridden equals() & hashCode().

So is very repeating operation to write code as:
Assert.assertTrue(list.stream().anyMatch(user -> user.name.equals(userName)), "list not contains user");
Assert.assertTrue(list.contains(user), "list not contains user");

I propose to add methods to simplify this action and convenient use:
Assert.assertListContains(users, user -> user.name.equals(userName), "user " + userName);
Assert.assertListContainsObject(users, user, "user " + user.name);

assertListContains uses a Predicate
assertListContainsObject uses contains() method of List

Did you remember to?

• Add test case(s)
• Update CHANGES.txt
• Auto applied styling via ./gradlew autostyleApply

Why not but we recommend to use assertj

You right, but nice to have a built in feature, because not always possible to add a new library)
