This patch adds an xfailing test reproducing a bug where when adding
an IF NOT EXISTS to a INSERT JSON statement, the IF NOT EXISTS is
ignored.
This bug has been known for 4 years (issue #8682) and even has a FIXME
referring to it in cql3/statements/update_statement.cc, but until now
we didn't have a reproducing test.
The tests in this patch also show that this bug is specific to
INSERT JSON - regular INSERT works correctly - and also that
Cassandra works correctly (and passes the test).

There is a difference how ScyllaDB and Cassandra handle conditional
batches with different IF statements (such as "IF EXISTS" and "IF NOT
EXISTS"). Cassandra tries to detect condition conflicts, and prints
an error instead of silently failing the batch, but in ScyllaDB
we considered this check to be inconsistent and unhelpful, and
decided not to implement it.
This commit:
- Make test_lwt_with_batch_conflict_1 scylla_only instead of xfail,
change the scenario to pass with the current implementation.
- Add test_lwt_with_batch_conflict_3 that shows how Cassandra fails
batch statement with different conditions, even when the conditions
are not contradictory.
- Add test_lwt_with_batch_conflict_4/5 that shows how static rows
are handled in conditional batches.
Fixes: #13011
Where the grammar supports IN, we add NOT IN. This includes the WHERE
clause and LWT IF clause.
Evaluation of NOT IN follows from IN.
In statement_restrictions analysis, they are different, as NOT IN
doesn't enable any clever query plan and must filter.
Some tests are added. An error message was changed ('in' changed to 'IN'),
so some tests are adjusted.

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.
