Create rule(s) for removed packages, classes and methods

Investigate if needed and create rules for the removed packages shown in [this section of the migration guide](https://github.com/spring-projects/spring-framework/wiki/Upgrading-to-Spring-Framework-5.x#removed-packages-classes-and-methods).

In the rule description and message, try to be as verbose and clear as possible. Code examples are always welcome and useful. Feel free to use markdown syntax for these.

Start with the “Removed packages, classes and methods” section of the Spring Framework 5.x migration guide and investigate which entries need rules. Done means rules cover the selected removals and provide verbose, clear descriptions and messages, with useful Markdown code examples where appropriate.
