Description

As an admin/a user, I would like to know the purpose of various config settings I see on the UI, so that I can make the correct changes to my cluster/topology.

This could be accomplished with a simple annotation for each key in our config classes, similar to those we use for validation, but just a simple string. The annotations could simply duplicate the text we already have in the javadoc comments.

The UI could send this text to the browser in as a tooltip pop-up when the mouse hovers over one of the config keys.
