    NIFI-3432 Handle Multiple Result Sets in ExecuteSQL

    This code change allows ExecuteSQL to handle queries that return multiple result sets.
    One existing unit test was failing and the results didn't make sense so I adjusted it.
Would be good to get a second pair of eyes on that.
    I performed hand testing against MS SQL Server. In some tests I had to enable `SET NOCOUNT
ON`. Results were as expected.
    I put some effort into building a unit test for Derby, but it's not simple... Derby doesn't
support submitting multi-statement requests in a single SQL statement, and Stored Procedures
are written in Java and require registration.  I tried putting one of these together but ran
into issues and decided to scrap it.

> ExecuteSQL processor only supports processing a single resultset. If a query/stored procedure
call returns multiple resultsets then only one is kept.
> ExecuteSQL should be updated to support handling multiple resultsets. When multiple resultsets
exist a flow file should be created for each resultset.
