PutHiveQL and SelectHiveQL Processor enhancements. Added support for multiple statements in a script. Options for delimiters, quotes, escaping, include header and alternate header.
Add support in SelectHiveQL to get script content from the Flow File to bring consistency with patterns used for PutHiveQL and support extra query management.

> Support Multi-Statement Scripts in the PutHiveQL Processor
> ----------------------------------------------------------
>
> Key: NIFI-3031
> URL: https://issues.apache.org/jira/browse/NIFI-3031
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Matt Burgess
>
> Trying to use the PutHiveQL processor to execute a HiveQL script that contains multiple statements.
> IE:
> USE my_database;
> FROM my_database_src.base_table
> INSERT OVERWRITE refined_table
> SELECT *;
> -- or --
> use my_database;
> create temporary table WORKING as
> select a,b,c from RAW;
> FROM RAW
> INSERT OVERWRITE refined_table
> SELECT *;
> The current implementation doesn't even like it when you have a semicolon at the end of the single statement.
> Either use a default delimiter like a semi-colon to mark the boundaries of a statement within the file or allow them to define there own.
> This enables the building of pipelines that are testable by not embedding HiveQL into a product; rather sourcing them from files. And the scripts can be complex. Each statement should run in a linear manner and be part of the same JDBC session to ensure things like "temporary" tables will work.
