The test is currently flaky, writes can fail with "Too many in flight
hints: 10485936". See scylladb/scylladb#23565 for more details.
We suspect that scylladb/scylladb#23565 is caused by an infrastructure
issue - slow disks on some machines we run CI jobs on.
Since the test fails often and investigation doesn't seem to be easy,
we first deflake the test in this patch by disabling hinted handoff.
For replacing nodes, we provide `cfg` because there should have been
`cfg` in the first place. The test was correct anyway because:
- `tablets_mode_for_new_keyspaces` is set to `true` by default in
test/cluster/suite.yaml,
- `endpoint_snitch` is set to `GossipingPropertyFileSnitch` by default
if the property file is provided in `ScyllaServer.__init__`.
Ref scylladb/scylladb#23565
We should backport this patch to 2025.2 because this test is also flaky
on CI jobs using 2025.2. Older branches don't have this test.
