Before this patch we silently allowed and ignored PER PARTITION LIMIT.
SELECT DISTINCT requires all the partition key columns, which means that
setting PER PARTITION LIMIT is redundant - only one result will be
returned from every partition anyway.
Cassandra behaves the same way, so this patch also ensures
compatibility.

Python and Python developers don't like directory names to include a
minus sign, like "cql-pytest". In this patch we rename test/cql-pytest
to test/cqlpy, and also change a few references in other code (e.g., code
that used test/cql-pytest/run.py) and also references to this test suite
in documentation and comments.
Arguably, the word "test" was always redundant in test/cql-pytest, and
I want to leave the "py" in test/cqlpy to emphasize that it's Python-based
tests, contrasting with test/cql which are CQL-request-only approval
tests.
