Feature/109

This PR adds a TDAF-compliant Conversion Pattern to log4j, including a transaction id. The README and some templates have been modified accordingly.

The issue #109 will be completed when all the traces are revised; this is necessary to create the alarm conditions table.
I'd suggest opening an issue about "log4j.properties consolidation: using same file for RPM and manual build" (techdebt - nicetohave).
