We already have in test/cql-pytest various tests for UDF in the bigger
context of UDA (test_uda.py), WASM (test_wasm.py) and permissions, but
somehow we never had a file for simple tests only for UDF, so we
add one here, test/cql-pytest/test_udf.py
We add a test for checking something which was already assumed in
test_permissions.py - that it is possible to create two different
UDFs with the same name and different parameters, and then you must
specify the parameters when you want to DROP one of them. The test
confirms that ScyllaDB's and Cassandra's behavior is identical in
this, as hoped.
To allow the test to run on both ScyllaDB and Cassandra, it needs to
support both Lua (for ScyllaDB) or Java (for Cassandra), and we introduce
a fixture to make it easier to support both. This fixture can later
be used in more tests added to this file.
