Some of the tests in test/cql-pytest share the same table but use
different keys to ensure they don't collide. Before this patch we used a
random key, which was usually fine, but we recently noticed that the
pytest-randomly plugin may cause different tests to run through the *same*
sequence of random numbers and ruin our intent that different tests use
different keys.
So instead of using a *random* key, let's use a *unique* key. We can
achieve this uniqueness trivially - using a counter variable - because
anyway the uniqueness is only needed inside a single temporary table -
which is different in every run.
Another benefit is that it will now be clearer that the tests are
deterministic and not random - the intent of a random_string() key
was never to randomly walk the entire key space (random_string()
anyway had a pretty narrow idea of what a random string looks like) -
it was just to get a unique key.

Instead of lengthy blurbs, switch to single-line, machine-readable
standardized (https://spdx.dev) license identifiers. The Linux kernel
switched long ago, so there is strong precedent.
Three cases are handled: AGPL-only, Apache-only, and dual licensed.
For the latter case, I chose (AGPL-3.0-or-later and Apache-2.0),
reasoning that our changes are extensive enough to apply our license.
The changes we applied mechanically with a script, except to
licenses/README.md.
Closes#9937
This patch adds a new cql-pytest test file - test_ttl.py - with
currently just a couple of tests for the "with default_time_to_live"
feature. One is a basic test, and second reproduces issue #9842 -
that "using ttl 0" should override the default time to live, but
doesn't.
The test for #9842, test_default_ttl_0_override, fails on Scylla and
passes on Cassandra, and is marked "xfail".
Refs #9842.
