removing Connection type parameter in getHostName method as jdbcTemplate...

Connection type parameter is passed to getHostName method JdbcEventWriter Class which is not used inside the method body as JdbcTemplate is used for processing the query.
Please note that : Even though  JdbcEventWriter is marked as deprecated there is no corresponding HibernateEventWriter implemented for Eventd package as it is done for Linkd. I am going to implement and submit a HibernateEventWriter for Eventd in a few days.

Thanks,
Nalla.
