Support compensating transactions for updatable non-XA sources

The transaction manager will fully support xa with all xa sources and a single local transaction resource. Beyond that however there is no built-in support for compensating transactions with non-XA sources. There has been work in Narayana on compensating transactions though that could be used by custom web apps consuming Teiid. We would like to eventually offer compensating options for some of our updatable non-XA sources, but it hasn't had sufficient priority yet.
