This requires: openrewrite/rewrite#533.

Partially, implemented in: openrewrite/rewrite@22f06ff.

Currently, the recipe does not rename all local variables.
The recipe does not rename fields that are local members of a class. since that would be pretty complex.

The recipe also prevents renames of variables if the result exists anywhere in the class to prevent unexpected name shadows.

It is possible to refactor the hasNameSet to use cursors and determine if will not create a shadow of a name, and rename variables safely.
