Refine the expected errors on each DDL operation

When executing a DDL, there are some expected errors where we don't want them to be retried, so the idea is to encapsulate the exception somehow to have something like the following:

try {

    ...<code> ...

} catch (const ExpectedException& ex) {

    throw NonRetriableException(ex);

}

This way we have a declarative way to tell the DDL coordinator will not retry this time because it is an expected error.
