> Add support for Java 8 specific q-test out files

> Hash function differences between Java 7 and Java 8 lead to result order
> differences. While we have been able to fix a good number by converting hash
> maps to insert order hash maps, there are several cases where doing so is
> either not possible (because changes originate in external APIs) or change
> leads to even more out file differences.
> For example:
> (1) In TestCliDriver.testCliDriver_varchar_udf1, for the following query:
> {code}
> select
> str_to_map('a:1,b:2,c:3',',',':'),
> str_to_map(cast('a:1,b:2,c:3' as varchar(20)),',',':')
> from varchar_udf_1 limit 1;”)
> {code}
> the {{StandardMapObjectInspector}} used in {{LazySimpleSerDe}} to serialize
> the final output uses a {{HashMap}}. Changing it to {{LinkedHashMap}} will
> lead to several other q-test output differences.
> (2) In TestCliDriver.testCliDriver_parquet_map_null, data with {{map}} column
> is read from an Avro table into a Parquet table. Avro API, specifically
> {{GenericData.Record}} uses {{HashMap}} and returns data in different order.
> This patch adds supports to specify a hint called
> {{JAVA_VERSION_SPECIFIC_OUTPUT}} which may be added to a q-test, only if
> different outputs are expected for Java 7 and Java 8.
> Under Java 7, test output file has (original) ".out" extension.
> Under Java 8, test output file has ".java8.out" extension.
> If hint is not added, we continue to generate a single ".out" file for the
> test.
