/**
 * Class that resets the abandoned timer on any activity on the
 * Connection or any successful query executions.
 * This interceptor is useful for when you have a {@link org.apache.tomcat.jdbc.pool.PoolConfiguration#setRemoveAbandonedTimeout(int)}
 * that is fairly low, and you want to reset the abandoned time each time any operation on the connection is performed
 * This is useful for batch processing programs that use connections for extensive amount of times.
