Add new Trafodion LOB Guide to documentation build and web site

An entry needs to be added to the incubator-trafodion/pom.xml file so that the new Trafodion LOB Guide will be built in the documentation build.

Once the guide does get built, we need a change to the Web page to link to it. The file that needs to change is documentation.md in folder incubator-trafodion/docs/src/site/markdown.
