Before this patch, if Scylla crashes during some test in cql-pytest, all
tests after it will fail because they can't connect to Scylla - and we can
get a report on hundreds of failures without a clear sign of where the real
problem was.
This patch introduces an autouse fixture (i.e., a fixture automatically
used by every test) which tries to run a do-nothing CQL command after each
test. If this CQL command fails, we conclude that Scylla crashed and
report the test in which this happened - and exist pytest instead of failing
a hundred more tests.
