The annotation-checker[1] module from the narayana rts/lra project should be moved under incubator repository[2].

The module was created ~4 years ago as a maven plugin with the purpose to help to verify if the LRA annotations are in right shape in the user project during build time.
That's an help to inform the user that when he use @Compensate @POST as a combination of annotations at his LRA compensate method that's a wrong combination which won't be processed.

It's rather a independent subproject than core functionality of LRA. It should be moved to a separate repo to clean the Narayana main repo to contain only core functionality.
