test: fix flaky sql tests
Summary
- test: fix flaky sql tests
At the moment clusterwide SQL has no protection from anomalies produced by vshard bucket rebalancer. We plan to fix it ASAP, but at the moment we need a stable non-flaky CI.
This patch makes tested cluster single-node. Multi-instance tests shall be added later in scope of fixing the mentioned rebalancing issue.
