Add relation exceptions (#12185)

Introducing a class of RelationException extending CustomException to
help grouping those exception in sentries by ExceptionCode.
I did not introduce a filter as these are thrown in utils that can be
used in multiple places now or in the future, and filters are to be
added at resolver-level.
