Introduce @Commit alias for @Rollback(false)

Due to common usage of @Rollback(false), this commit introduces a new
@Commit annotation that more clearly conveys the intent of the code
while retaining the run-time semantics.

@Commit is in fact meta-annotated with @Rollback(false).

Issue: SPR-13279
