[Registry-dev] Transaction support in the registry

[Chathura C. Ekanayake]

+1. I am already implementing transaction functionality in the 
JDBCRegistry. We can introduce transactional methods to the API.

registry.beginTransaction();
registry.rollback();
registry.commit();

Once these methods are added to the JDBCRegistry, APP interface can 
simply call these methods to perform set of actions remotely within a 
transaction.

Thanks,
Chathura
