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.
