IMPALA-12373 introduces small string optimisation, after which not all strings will have a var-len part. IMPALA-12159 adds support for ORDER BY for collections of variable length types in the select list, but the test tables it uses only/mostly contain short strings. This patch has two modifications: 1. It introduces longer strings in 'collection_tbl' and 'collection_struct_mix'. It also adds two more rows to the existing one in 'collection_tbl' so that it can be used in sorting tests. These tables are only used by complex types tests, so the impact is limited. 2. It modifies RandomNestedDataGenerator.java, so that now it takes a parameter for string length. Some variable names are changed to clearer names. The references to and uses of RandomNestedDataGenerator are updated.
