by default, up to 3 temporary directories are kept by pytest.
but we run only a single time for each of the $TMPDIR. per
our recent observation, it takes a lot more time for jenkins
to scan the tempdir if we use it for scylla's rundir.
so, to alleviate this symptom, we just keep up to one failed
session in the tempdir. if the test passes, the tempdir
created by pytest will be nuked. normally it is located at
scylladb/testlog/${mode}/pytest-of-$(whoami).

Closes#14735
[xemul: Withdrawing from PR's comments
object_store is the only test which
is using tmpdir fixture
starts / stops scylla by itself
and put the rundir of scylla in its own tmpdir
we don't register the step of cleaning up [the temp dir] using the utilities provided by
cql-pytest. we rely on pytest to perform the cleanup. while cql-pytest performs the
cleanup using a global registry.
]
instead of using a single run to perform the test, restructure
it into a pytest based test suite with a single test case.
this should allow us to add more tests exercising the object-storage
and cached/tierd storage in future.
* add fixtures so they can be reused by tests
* use tmpdir fixture for managing the tmpdir, see
https://docs.pytest.org/en/6.2.x/tmpdir.html#the-tmpdir-fixture
* perform part of the teardown in the "test_tempdir()" fixture
* change the type of test from "Run" to "Python"
* rename "run" to "test_basic.py"
* optionally start the minio server if the settings are not
found in command line or env variables, so that the tests are
self-contained without the fixture setup by test.py.
* instead of sys.exit(), use assert statement, as this is
what pytest uses.
