IMPALA-12570: Add longer strings to tables containing collections
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.
