Add wrappers for legacy addons supported by RHPAM 7.11

After renaming the addons on KOGITO-5299, would be good for users if we keep the old artifacts dependent on the new ones. By doing that, projects referring to the old artifacts still work.

These addons should have a startup service adding a WARN like:

> you are using legacy dependency and this will be removed in future release, please update pom to use XYZ

These are the artifacts that we need to add legacy wrappers:
